>> you know, whether you're a muggle, a half-blood or a full blown wizard, it may be hard to believe that one of hollywood's most successful film franchises ever is about to come to an end. from books to movies to a theme park in orlando, j.k. rowling's story about a young wizard and his adventures has become a pop culture phenomenon. the statistics are staggering. over the past ten years the seven films have made some $6 billion. tonight you'll hear secrets from the set. you'll see how the wizarding world was brought to the big screen. we'll even show you an exclusive never-before-scene clip of the final movie just days before it open. first a look back on how it all

began. >> be safe. be strong. >> larry: harry potter, the boy who lived, faces his biggest challenge yet. a final showdown with the dark lord voldemort. an epic battle ten years in the making. the last harry potter. how's that feel? >> you know, very, very strange, considering we've done it for ten years. but it's also a wonderful feeling of achievement and particularly i'm very, very proud of this last film and i think it's the best out of all of them, i think, and you know, i'm very, very excited. >> larry: also excited, millions of harry potter fans around the world who have been waiting years for the finale. >> from what i could see just shooting it, i knew it was -- pretty epic. it's -- i think we -- we do it justice. i definitely -- yeah, we do. >> now, join me, harry, and

confront your fate. >> very serious. rising again and really quite disturbing. we're losing characters we've known since the first book, and it's -- yeah. i think it's going to be really shocking just to see the castle collapse into this kind of burning piles of rubble. >> come on, tom. let's finish this the way we started -- together. >> larry: "harry potter and the deathly hallows," part two, is sure to be the biggest movie event of the summer. we'll give fans the ending they have been waiting to see since we first met the wizard in 2001's "harry potter and the sorcerer's stone." 2 was ten years ago for the very first time we able to see the wizarding world that until then was only imagined in books. >> and courage i see. not a bad mind either. there's talent. >> up. get up! >> larry: we laid eyes on harry potter.

an orphan made to live in the cupboard under the stairs by his aunt and uncle. >> there's no such thing as magic! >> you won't believe what this snake is doing! >> larry: tormented by his cousin. feeling isolated and alone, who found out he was not only a wizard, but the most famous wizard of all. we were also introduced to his two best friends. >> oh, are you doing magic? >> the booksmart, know-it-all hermione granger and harry's sidekick ron weasley. >> turn this stupid fat rat yellow. >> larry: the books and seven movies so far have made stars out of the three then unknown child actors. daniel radcliffe, emma watson and rupert grint. they have grown up before our eyes. >> it's really strange. that's the only way i can describe it. it's -- it's been -- i mean -- i

was so young, it's difficult to remember much of my life before this thing happened to me. so it coming to an end is, you know, it's huge. i was 9 years old. you know -- i was still losing teeth. if that puts it in perspective. i was still losing baby teeth. >> larry: the first film was an instant hit for warner brothers, which, like cnn, is owned by time warner. that wasn't a surprise. by then harry was already a household name around the world to the millions of fans of the books. and it was all dreamed up by an unlikely author. j.k. rowling, who at that time was a single mother on welfare when she came up with an idea about a boy who does not know he's a wizard. >> do you remember how -- it's impossible to say how an idea came about. >> uh-huh. >> do you remember, though, the creation of this concept? >> yeah. it came to me on a train going

from manchester to london in england and it came very suddenly. >> what came? >> the idea for this boy who didn't know what he was, and until he was 11 and then got this invitation to go off to wizard school and i had this very physical response to the idea. i felt so excited. i just thought it would be such fun to write. >> the first book released in 1997 marketed as a simple children's book by a first-time author. many people including rowling herself did not have high hopes for it. >> in all honesty i didn't think it would do this well with anyone. i thought i was writing an obscure book that, if it ever got published maybe a handful of devoted. i thought it is kind of a book for obsessives. i thought maybe a few people would like it a lot. i never expected it to have broad appeal. >> rowling, turned down by several publishers after she wrote the first book, has become one of the richest women in the world. so successful, she's reportedly surpassed even the queen in wealth. rowling's story spawned seven best-selling novels which sold

more than 400 million copies. the books are available in 200 countries, and have been translated into some 70 languages. each release of a new novel was cause for celebration for fans who lined up days in advance to be the first to walk out with the latest story. but in 2007 when rowling released the final chapter of the series, "harry potter and the deathly hallows," we knew it would eventually come to this. >> the boy who lived, come to die. >> larry: harry and voldemort's final stand. the last harry potter movie ever. you said this one, the one opening later this week is the best. >> uh-huh. >> larry: why? >> because it's the most exciting. i think it's the most direct.

i think we did so well in film 7 part one by setting up all the fl plot that people need to understand this second film that we can just dive straight in and give people this, and what's -- i think in this film we find the balance best between the emotional side of films and the action-packed adventure exciting side. i mean, i think -- i think we've never got the balance so right before. >> i would agree. it's a hell of a movie. >> it is a hell of a movie. >> avada kadavra! >> coming up, an exclusive clip from the final harry potter film you won't see anywhere else. plus -- we'll show you how ralph fiennes went from this to this. next, daniel radcliffe reveals what happened on the last day of filming. >> i kind of wept like a child. >> larry: when this special,

producers set out to find the perfect boy. >> dan is great. it was a very difficult process. finding harry was very hard. it was like trying to find scarlet o'hara. i think everyone was getting slightly desperate. i was walking down the streets of edinborough looking at them in a suspicious way. could it be them? and they walked into the theater and they found dan. dan is an actor. he's just perfect. >> dan, of course, is daniel radcliffe. up to then, his biggest role in the biggest miniseries "david copperfield." his parents have some connection to the industry tried to keep him from trying tout to the potter movies. unbenoent to producers, they had repeatedly asked the boy's parents if he could audition. not wanting the obligation of this role to disrupt his childhood, they declined.

eventually, fate stepped in one night at the theater. >> i was sitting in the theater and with my mom and dad and in front of us was sitting david hyman and the screenwriter steve clovis and i was completely unaware why this man kept turning around and looking at me and staring throughout the show. i didn't know what to make of it. then i remember my dad and mom getting quite flustered and eventually, that was the moment they said, maybe this is just meant to be. let's let him audition. >> larry: how did they tell you that you got it? >> i was in the bath and my dad -- my dad got the phone call downstairs and came in and said, you got the part, and i was just very, very happy. >> how old were you? >> i was 11. i think i just turned 11. yeah. had no idea what the implications were. but knew it probably meant i bought myself an extra half hour before i had to go to bed that night. >> larry: radcliffe's life was about to change forever.

did you have a normal boyhood? >> it's very hard to say. i mean, no. i suppose is the official answer. i certainly didn't have normal teenage years but equally i don't really know what normal means. i mean, was i happy and healthy and surrounded by fun and love? yes. and that's kind of all right with me. i was surrounded by inspirational interesting people from a variety of different backgrounds. >> so many child stars, for want of a better term. kids who become famous early, have major problems. >> yes. >> larry: you didn't. can you explain that? kids are not supposed to be famous at 11. >> no. they're not. what i'd put it down to is the fact that i think it's very different doing it in england than it is doing it in america. when you do it over here you are treated as a star first and a

child second. whereas in england it's the other way around. you're treated as a child first and then an actor in the film, but i don't think anyone panders to it as much in england as much as they do in america, but thankfully i haven't gone massively off the rails. >> larry: have you enjoyed it? >> oh, yes. absolutely. immensely. where there have been moments, i'd be lying if i said every single day was fantastic. generally speaking, i just had the best time. i got to work with my best friends every day. >> larry: you like harry? >> yes, i do, very, very much. >> larry: anything you don't like about him? >> yes, of course. he's kind of -- kind of arrogant, and pretty selfish at times. not so much in the later films, but -- also i think there's often a little bit of the smell of burning martyr in harry. he kind of -- he occasionally, i think, likes to, the fact that

it's all on him and i think snape says about harry that he seems to relish his fame. that's not completely true he does have a hero complex and i think he thinks he always has to be -- >> larry: he's the captain. >> absolutely. which i suffer from myself sometimes. >> larry: really? >> i think so, yes. >> larry: not wanting to be typecast forever as harry potter, radcliffe began branching out. in 2008, made his broadway debut in "equus" appearing naked onstage and today stars in "how to succeed in business without really trying." it's so not what you would expect from you -- dancing, singing, jumping. >> absolutely. anyone who knows me would expect the jumping, but dancing and singing. yeah. it's something completely different and i -- you know, i've got the energy to do it at this age so i might as well be doing it. also, i do think there's, as an actor -- i don't think you'll

ever work that much harder than doing a broadway show. particularly a musical eight times a week. so, yeah. i like working hard. that's the other thing that potter has instilled in me. a work ethic that i now -- i love to work. >> larry: how have you kept a balance through all of this? >> the most important thing for me to remember is it doesn't matter who had gotten this part, they would have been receiving this kind of attention. this much -- you know, when you step out of the car and you get hit by that wall of noise, of screaming, you have to -- it's very important for me to remember that would be screaming for somebody else if he got the part. it's not about me. it's about the franchise and the character. so that i kind of have to think about to help keep it in perspective and stop myself from getting big headed. >> larry: coming up next, a behind-the-scenes exclusive,

>> larry: j.k. rowling created a unique world with the pages of

her harry potter books. a world where cars fly -- wall portraits talk -- ♪ >> larry: books try to eat children. magic spells are cast with the simple wave of a wand. >> fantastic, ginny! >> larry: and where ralph fiennes transforms into voldemort. we'll show you more of this exclusive footage in just a moment. >> it's a really interesting -- there's an awful lot of very complex challenges in the potter books, and j.k. rowlings writing is great and she gives a lot of good description. writing it down on the page and translating that into a moving image is difficult because everybody has an idea when they read the book of what something might look like. >> larry: tim burke has been the visual effects supervisor on the harry potter films for the past

eight years. his job, trying to make everything that happens at hogwart's look real. >> i think visual effects in harry potter go hand in hand, and you can't make the films without them. >> larry: burke leads a team of hundreds of wizards who make movie magic on the big screen. >> i don't think the audience would realize quite how many effects there are in the films. especially down to the environment. it's quite startling when we show people what was actually shot with an actor in front of a green screen and then what is in the final film and he's standing in the scottish highlands. it often surprises people. >> what's down there? >> thankfully all three actors, they basically learned how to act on terrible green screen stages with nothing else to work off which is essentially for us. it's only through their performance that you can really believe that world existed when we added it later on.

>> larry: out of the roughly 200 creatures burke and his team created for the films he has his favorites. >> most of them are probably animated characters. when we did the hippogriff on the third film, that was a very big technical challenge. maybe it would be easy to do now. at the time it was a very difficult complex thing to do but it was a very big character in the film, and we had to do a lot of complex things involving harry having to ride and then fly on the back of it. so realizing and completing that for the film was quite an achievement. and more recently i really, really thought that the work we did with kreature and dobby was sort of topnotch. because, you know, you had to empathize with these little cg characters to the point where you really had to feel harry's emotional distress when dobby died at the end. to do a cg creature that causes

the audience to shed a tear is quite a challenge. i think we managed to pull it off. that was quite a difficult thing, but, very rewarding as well. >> larry: but for every rewarding visual challenge there are some effects that burke says have fallen flat. >> some things, you're pleased with other things that never quite were at good as you hoped, and i think for me, if i'm completely honest it would probably be grawp in the fifth film. didn't quite hit the mark unfortunately. we weren't really quite sure how believable he was at the end of the day. that was very difficult, to be honest, and you know, can't win them all. so -- >> larry: one of the most important transformations tim and his team have done, turning ralph fiennes into the dark lord voldemort. seen for the first time publicly, we're able to show you how it was done. >> we mastered the technique over the years and basically ralph fiennes wears makeup,

prosthetic makeup and a matrix of dots cover the area of his face that we have to replace with our digital prosthetic. and we filmed him in all the action sequences and all the drama pieces just normally, and then remove his real nose in the computer afterwards and replace it, after we've tracked the movement of his head in the computer, we replace it with our snake nose and that actually is animated. there are moments when we flare the nostrils to emphasize a point when he's speaking or talking. animation goes into that as well, but it all has to be relit textured to look like it was his real skin. that's done through a lot of sort of reference photos that we take for every set where we film him on and we use those to help light the skin. >> larry: another one of burke's favorite effects, the book of

monsters from "harry potter and the prisoner of azkaban." >> this a great sequence where the book actually comes alive, and tries to get harry when he's at the leaky cauldron. this was cone with a combination of a practical, animatable prop that could actually open its mouth. the idea is it's got these teeth here, and can you actually see it snap and try and get harry. it was a great, fun scene where he's trying to -- well, the book's trying to eat him and we've got a combination of cg animated book and the practical book on the set. and we animate all of these little tentacles as well. so that was something that we could film practically on the set with dan and a real animatable book, and then also there were times when we replaced the book itself with a cg one. >> larry: there have been thousands of computer generated

effects in the eight "harry potter" movies but burke hopes you haven't noticed that. >> we often say if you don't spot the effects you've actually done your job well. the real reward is when people don't realize you're watching effects. especially with something like harry potter. >> larry: up next, rupert grint turns the tables on emma watson and daniel radcliffe and asks some questions of his own. >> maybe they want to know on the last day i brought them both a trumpet, and, yeah. why a trumpet. >> larry: and later, robb robby coltraine and helena bonham carter er revealing secrets from behind-the-scenes. >> 25 takes. i just thought, you have know idea what's happening down there. >> larry: on this "larry king" special, "harry potter: the final chapter."

>> i'm don lemon. here are your headlines. president obama will hold a news conference at 11:00 a.m. monday to update on the debt ceiling negotiations. he and congressional leaders met sunday at the white house but the meeting lasted only a little over an hour. the government maxed out borrowing at $14.3 trillion.

"atlantis" is delivering supplies and spare parts to the international space station. it will return to earth in two weeks marking the end of nasa shuttle programs. those are your headlines. i'm don lemon. keeping you informed. cnn, the most trusteded name in news. hi there. i'm tom felton and i'm in the "harry potter films." it's been an incredible ten year, and i've been very, very lucky to have been at hogwarts for the last ten years. thank you very much and i hope you enjoy the last film. >> larry: in "harry potter and the deathly hallows part 2" gone is the innocence of childhood. harry, hermione and ron face real danger. life and death. >> a different film, really. it's all kind of quite tense. i think people will be shocked

by how brutal it is. >> i mean, it was -- the last two films were dark for me to play them, and to be in that world every day. and we did so many scenes where there was so much adrenaline and fear required. it was really intense. genuinely. >> larry: like millions of children around the world, both emma watson and rupert grint were huge fans of harry potter. >> whenever i was reading the books i always felt a strong connection to ron. i even entered a lookalike contest that was in the paper. yeah, i won the best ron. >> i loved those books. my dad used to read them to my brother and i. i just loved them, and i always, always loved hermione. >> larry: watson and grint have spent almost half their lives playing her mie- -- hermione and

ron. now with the release of the final film, they look back to the beginning. >> the first audition, when i first met dan and emma and, yeah. it does seem like a, such a long time ago. >> nicholas flamel is the only known maker of the sorcerer's stone. >> the what? >> hermione reading, a scene from the forbidden section of the library, and, yeah. i just remember, my voice, i was really kind of quiet. >> larry: the three young stars have gone through so much together. becoming famous the world over at such a young age. >> it's been 11 years of quite an intimate process. where you are kind of with each other every day, all year, every year. it's quite a unique kind of thing we've kind of shared with each other, i think. >> larry: so what do they really think of each other? >> dan. he's -- always been quite hyperactive.

quite loud. he's very funny. >> dan is the most energetic, hard-working, kind person. he works very, very hard. so he's pretty incredible. >> yeah. me and emma used to do things all the time. she's great. she's really kind of caring. >> he's a real eccentric. he's a genuine eccentric. i've never been to his house, but i would love to go, because it just sounds like it's full of the most magical, wonderful and weird thing. he has llamas and miniature pigs and he's bought a hovercraft and he has a cow on one of his roofs in his house in london, and he bought an ice cream van that genuinely works and it's funny. because he's this very quiet guy but kind of just loves crazy

stuff. >> larry: did you hit it off with emma and rupert right away? >> yeah. >> larry: you grew up together, right? you bonded. >> rupert and i particularly. emma was always the -- you know, the kind of -- when it came to preventing us from laughing on set, she was the best. rupert and i were terrible. >> larry: during our interview, rupert had some fun and decided to ask some questions of his own. >> maybe you want to know, on the last day i brought them both a trumpet. and, yeah. why a trumpet? >> larry: do you know why? >> i just -- because he's mad, and he's rupert. i imagine. i don't know. >> larry: he's crazy? >> i didn't know if there's was a reason. >> larry: there's no reason to a trumpet. >> okay, dan, have you ever considered dyeing your hair ginger? >> yes, but only for him.

>> larry: in a private moment. >> at his request i would do that. >> larry: and for emma? >> emma. who do you like best? me or dan? >> of course. neither. i don't think either of them are that great. no, i'm joking. obviously i love them both equally because that's the diplomatic answer. that's the right thing to say. >> larry: like their characters emma and rupert have grown up in front of the world but unlike ron and hermione, they had to deal with the fame of who they are and what they represent to millions of fans. >> give me like presents and stuff and just touch me. really weird. that side of it has taken me a while to kind of get used to. >> some little children are sometimes scared of me because they think i can do a spell that i really am magic in real life

and i've always found that really funny and i try and kind of say, i'm not going to do anything to you. it's okay. sometimes you can't convince them, because they believe in it. they really believe in it. >> larry: and now that it's over, the world and these actors prepare to say good-bye to harry, hermione and ron. >> quite a shock, really, leaving it behind. i wasn't prepared for how it would feel and how much it meant to me. >> it's been pretty great to grow up being her though i wasn't spending that much time being me. i really do understand that and realize that and feel good about it. yeah. i think we're very lucky. definitely. >> larry: still ahead, james and oliver phelps take us on a tour of the wizarding world of harry potter and talk to fans on the eve of the final film.

>> just seeing their faces, they are in awe of it. shows what it means to people. >> larry: plus a scene you won't see anywhere else, and daniel radcliffe talks about what's next. >> i want kids and i want a lot. i absolutely do. >> larry: on this "larry king special -- harry potter: the final chapter." from cheerios to lucky charms, there's whole grain in every box. make sure to look for the white check. there's whole grain in every box. ♪ sing polly wolly doodle all the day ♪ ♪ hah

how big an outfit is it to get into? >> it weighs about 110 pounds, i guess. and there was no way around that, because it just had to look absolutely right. >> larry: do you like hagrid? >> i do like hagrid, yes. he's a sort of -- a very good question. nobody's asked me that before. yes, i do like hagrid. he's a big decent kind of bloke. >> hagrid. >> oh, hello. sorry. i don't mean to be rude. i'm in no fit state to entertain today. >> we know about the sorcerer's stone. >> larry: coltrane was her first choice to play the giant, that his acting brought a subtlety necessary to the character. >> with all the fans that this, these books have and the films, do you feel an enormous responsibility to get hagrid right? >> yes, i did feel an enormous responsibility to get hagrid right, but i also think everyone else did. i'm talking about the sparks and the woodworkers and the construction people. everybody. because they're all parents, too. they'd all read the books to

their kids. i think everybody raised their game and you look at the cast list of all the people we've had over the ten years. you know, it's the absolute who's who of british acting. it's been an extraordinary experience for everybody, i think. >> larry: one of the latest additions to that who's who of british actors, helena bonham carter, as bellatrix lestrange. >> serious mental issues. a sociopath or psychopath. she definitely takes pleasure from pain which makes her definitely very, very sick. >> larry: bellatrix has been a potter fan favorite since she was introduced in "the order of the phoenix." >> great fun to play, because i just go to work and it was amazing to be paid for over a period of four years to go to work and be paid lots of money to wait around and play a witch and be really naughty. >> larry: in the final film there's a pivotal scene at the ends of the movie. a final fight during the battle

of hogwarts with ron weasley's mom, something carter says fans will look forward to. >> we had a duel, and one duel. it's a bit like fencing but without actually making contact. it was really hard work and me and julie, we definitely needed the chiropractor after. it's very easy to throw your shoulder out. >> we won, we won, we won! >> larry: carter is not one to hold back. when we asked to tell a secret from the set, she opened the floodgates. >> i did wee wee. don't tell anyone. >> larry: seems after giving birth and returning to work, her bladder wasn't what it used to be. >> i'm barely able to stand up less alone stand up and scream. anybody that's had a baby, if you scream and you just had a baby, nothing -- your -- everything, you know, it's niagara. after 25 takes, i just thought, you know, you have no idea what's happening down there. larry -- you did ask me.

>> larry: carter's played many quirky characters over the years but said she has an affection for bellatrix and her time on harry potter. >> i loved it and felt it's a real privilege and an honor to be a part of it. to be part of something it so stimulates the sort of mass imagination across the world with children. and to feed on people's imaginations. and to even -- it's in some way exciting for them. >> avada kedavra! >> larry: from the wizarding world on the screen to the wizarding world of harry potter at universal studios, florida, where in the past year, millions of potter fans have gone to get an up-close look at where harry and his friends called home. >> it's great. you can walk around and there is snow on the rooftops. brilliant. >> just seeing all their faces, they are in awe of it.

shows how much it means to people. >> larry: we asked james and oliver phelps better known at fred and george weasley to give us a tour of the park from dumbledore's office. >> the actual books on here are actually all detailed in wizarding matters. >> larry: to olivander's wand shop. >> perhaps this. >> cheers. >> larry: to getting a butter beer. >> in love with you. >> larry: and as you can imagine, the fans took notice. >> i feel walking around here, people walking up to us and talking to us like we're fred and george which is pretty neat. >> people taking photos and everything. it's quite surreal, really. it's nice, but surreal. >> larry: the phelps like the rest of the cast say they're sad to leave harry potter behind. >> very surreal on the last day to walk out. we had a great time doing this. the last day of filming was

quote emotional for us. it's bittersweet. we're aware we are coming to an end now and what a better way to go out than on the biggest high. >> our work is done. >> larry: find out what happened on the last day on set. >> it was very sad. yeah. we all cried. it was really, really bizarre. >> larry: as daniel radcliffe, emma watson and rupert print say good-bye to harry potter. plus, your exclusive look at a scene from "harry potter and the deathly hallows, part 2." it's all next on a larry king special, "harry potter, the final chapter."

>> larry: ten years in the making. and soon we'll see the last of harry potter. >> avada kedavra! >> larry: and in just moments we'll show you an exclusive clip of the final movie. from the beginning this story of a little boy who didn't know he was special has touched millions of people around the world.

>> why is it so successful? >> i think it's due to a lot of things. it's -- we love an underdog. i think the world of j.k. rowling is so meticulously thought out that people like me, who like to geek out about these things can get wrapped up in the wizarding lore and the world and it's so complete. i think we love that. we love the magic. we love the idea of that. and they're just -- it's a testament to just the brilliance of the writing. >> i really love, and what i think the people really love and why the stories are so enduring and why they touch so many people is because the characters are so -- so real and flawed and beautiful and inspiring and lovable. just completely lovable. >> larry: as actors, crew members, and fans prepare themselves for the end of harry potter, a few statistics.

in the past ten years harry's famous lightning bolt scar has been applied to daniel radcliffe's forehead an estimated 2,000 times. 588 sets have been created. and harry has gone through 160 pairs of glasses and some 70 magic wands. but as the final potter film is about to open, all that is now history. >> what was the last day like? >> very, very emotional. i remember i kind of wept like a child on that last day. >> it was kind of like the last day of school. and i remember packing up the dressing room. it was very sad. we all cried. it was really, really bizarre. >> larry: as the cast moves on from harry potter, they share thoughts of their past and of their future. >> it's definitely going to kind of be with me for the rest of my life, really. but yeah. i'm really just grateful to be a part of it.

i've loved every -- every day of it. >> it's bittersweet. you know, it's really exciting to see what's -- you know, what comes next. but it's definitely a big chapter closing. >> larry: and for daniel radcliffe perhaps a chance for him to share his unusual childhood with his own children. >> do you want family someday? >> oh, god, yes. absolutely. i'm one of the -- it's very strange. i'm one of the broodiest young men you will ever met. i think also because i spend so much time around adults and i saw them all have kids -- >> you want children? >> oh, god, yes. absolutely. i want kids and i want lots. >> but you know you need someone else in order to -- >> i need to get someone who's willing first, yeah. >> share their life with you. >> yeah. i mean, i've -- you know, i've got a girlfriend at the moment who i am very much in love with. so you know, we'll see where that goes. >> larry: as we leave you tonight, here's your first look at a never seen before clip of

"harry potter and the deathly hallows: part 2." >> how did you come by this sword? >> it's complicated. why does bellatrix lestrange think it should be in her vault at gringott's? >> it's complicated. >> the sword presented itself to us in a time of need. we didn't steal it. >> there is a sword in madam lestrange's vault identical to this one, but it is a fake. it was placed there this past summer. >> and she never suspected it was a fake? >> the replica is very convincing. only a goblin would recognize that this is the true sword of griffindor. >> i need to get into gringotts into one of the vaults. >> it is impossible. >> alone, yes. but with you, no.
