nervous. i'm pumped and excited, but a little bit nervous. we've arrived at the hospital in la paz, in madrid. we are here to meet the kids fighting cancer.— we are here to meet the kids fighting cancer.- why i we are here to meet the kidsi fighting cancer.- why is fighting cancer. hello. why is that? well, — fighting cancer. hello. why is that? well, it's _ fighting cancer. hello. why is that? well, it's because - fighting cancer. hello. why is that? well, it's because i'm l that? well, it's because i'm about to play some video games with them. this year is my new friend marco. how long have you beenin friend marco. how long have you been in the hospital? pokemon? i love pokemon, as well! can i get my pokemon, can i show him? you want to play? go for it, man, check out my pokemon. now we arejust here man, check out my pokemon. now we are just here playing games for the sake of them, but rather it set to reduce the pain that leaves the lack of these kids feel. a hospital has been studying these children

and the adverse effects of chemotherapy. the nervous system unconsciously... breathing, blood pressure, heart rate. so doctors can at a glance see the level of distress a patient may be in, but lower the number out of 100, the more they are in. it quantifies pain. we looked at this machine last year where doctors said it helped assess how much pain someone was actually in. so they can administer the right amount of pain killers so as not to overall undergoes them. it was critical treating coven patients —— go red patients, as well. now they are using it to try to prove one of those popular theories around. there have been various studies over the years looking into the relationship between gaming and pain. and by using this machine, they can objectively say when someone is feeling more or less pain. but why are

video games having this effect? the effect of a video game is not only. now this trial has been peer—reviewed and published in the journal of peer—reviewed and published in thejournal of medical research. they had 20 kids in total playing video games for an average of 2.3 hours every day, and that was enough to bring about less pain and less need for morphine, showing how effective this nonmedical, noninvasive hobby may be. me personally, i usually get vexed with video games if things don't go my way. but for these kids, not so much. the theory is that adolescent kids can gain more pleasure from video

games than any other age range. i imagine he's in pain right now, but it doesn't matter because he's just fully absorbed. right now, this is all because of that. daniel here, for instance, was one of the first trial lists. and he immediately saw the benefit. and it all began when this psp was handed to a patient. and

they similarly noticed how a fix to the kid was to it. now they want to take their findings further. so maybe one day we will find play stations and nintendo

called tech war some years ago, i directed a pilot film. it's sold as a series. it lasted a year, and now i'm attempting to go with a very well known animation house to sell it as an animated series. and it's tough. i've got a game show that's so unique, and i'm trying to sell that. so one thing after another, it's very difficult. it's almost impossible to sell anything... even with you attached? wow. notjust me, but people who are, you know, i mean, starting from the beginning, you need the money to make the movie. now that's where legion m comes in, because they're now... their basis is, "let's ask people to contribute money to making a film," they'll own a minute part of it based on their small contribution, which is what i believe everybody wants.

we want everybody to contribute a little tiny sum of money. they then have a little tiny partnership in the movie, and they also can express their opinion of the movie. and the movie is being made by supreme professionals being guided by the opinion of this large group of people whojoin in on film scout or legion m, those apps. i guess you can listen to the opinion of the people who are contributing, but i guess you also don't have to follow their opinion if you know better. you know, is it always a good idea to follow the opinion of everyone? the premise is we don't know better. who knows better? if 1,000 people say, "that's funny," and you think, "that's not funny," you have to think, "that must be funny," because 1,000 people thought it was funny. 10,000,100,000 people say,

"you know, what we're interested in is x," and you think, "x is not interesting," you have to bend. i think it must be unusual for someone who's been in the business as long as you to still be that open to public opinion. i would have thought that most people would kind of think they know it all by the time they've worked that long. that's where you gentrify. that's where you become so rigid that you think, "i know it all," and then you're dead because you don't know it. that's the final evolution of me at any rate. you finally go, "oh, i know how to do it. no, i don't." and finally, you come to whether it's sad or glad, the fact that i really don't know anything. and now you become open, not only to laughter and tears, but open to the leaves on the trees. i mean, now you become... ..almost, you know, show business then becomes almost spiritual in a way.

i've met a number of astronauts through this programme. they said they saw earth from up there and it changed them, and ijust wondered whether you'd had the same experience. i was filled with grief because i saw how vulnerable all of this is and not only saw it, we look around us at things that are falling apart in nature because of man, we're destroying this incredibly beautiful... this earth is filled... everything about earth is beautiful, and it's evolved over five billion years. it's taken five billion years of, "oh, this not working — i'll go onto this." you ever think about nature doing a display the way... ..the way people are trying to sell... ..entertaining the vehicles? so nature is saying, "all right.

let's see. maybe this will go." and nature does... and the supreme nature doesn't buy it. "no, that's not going to work." so nature's filled with things that are not working, and it goes away and another thing takes it. "oh, that works." and the show business of nature and it's all beautiful because it's all evolved and we're bloody destroying it, and itjust filled me with such grief. it took me so long to get... to be able to handle it. and that's where i'm at. william shatner, what a legend. i know. you know the best thing about that interview? what? he turned up early, and he talked for longer than he said he would. oh, who wouldn't want to hang out with you? well, from one movie icon to an iconic movie. so, over the last few weeks, we've been looking at some of the films nominated for best visual effects at this year's oscars, and this week it is the turn of james bond. did you know that no time to die is the first bond movie that's been nominated in the best visual effects

category in 43 years? moonraker was the last one in 1979. yes, of course. and here is some of the amazing work that went into the film. now your enemy is my enemy. his name is safin. and what does he want? revenge, me. the bond films have a rich heritage of shooting all of their extraordinary action for real. and this film was absolutely no different. there was visual effects in it, but they were not up front and centre. so, for instance, in the norway lake sequence, the production actually went to norway and they filmed on a real lake, a real frozen lake in norway. but as with any production, when you shoot throughout the day, the footage looks different from shot to shot. there was kind of one or maybe two shots, which everyone was happy with the lighting conditions.

we had a task to try and match the lighting across all of the shots. and in order to do that, we simulated a c6 world where the lighting was exactly the same. and then we used a number of techniques to copy and mimic what we were seeing in the computer. so rather than... we still used the photography and built on top of it rather than replacing it whole hog. but we used the simulation to tell us what that should look like. the director, cary fukunaga, is very keen to keep as much of the stuff that he had shot as he could. that included the people, that included the buildings, the trees even, but the trees didn't have snow on. so each tree had to be, particularly for the close—up trees, it had to be modelled in c6! to look exactly like the trees that were there. we put snow on them digitally, but then lifted the digital snow off and put them on top of the real trees that

were in the plate. we had, you know, an amazing special effects team that really did, and stunt team, that really did jump land rovers through the air. and when we needed to replace things like that for lighting or for filling in the background, we kept exactly that stunt. so on a james bond film, no—one really wants to resort to c6! stunts and things like that. so they really do capture everything in camera. but when they, for sort of timing reasons, they take a chunk out of the middle of a chase, suddenly, the continuity of where those vehicles are and where they need to be sort of goes out the window. that's when we do come in and we find a plate that maybe has got the toyota in it, which is bond's car, but it doesn't have the land rovers there, so had a motorbike. so we'll erase the motorbike, but we'll put the land rovers in and that's the kind of work

that we are doing. it's not very flashy work to put in the grass that was completely chewed up by the stunt team and to replace that, but it does need to be... it does need to look really accurate and the attention to detail that our environments team had to go to to model the tufts of the grass that matched the scottish highlands where they were shooting. unless we go to those sort of lengths, you don't end up believing it and it all feels like a bit of a fudge and we're not interested in fudging it in, you know, 2022. not that long to go now till the oscars. i think the question everyone is asking is, "can dune do there what it did at the baftas recently?" what's your prediction? i'm team spider—man.

ooh, interesting. anyway, that is it from us for this week. as ever, you can keep up with the team on social media. find us on youtube, instagram, facebook and twitter... thanks for watching. we'll see you soon. bye—bye! hello. at 17.5 celsius in west sussex, on friday it was the warmest day of the year so far. no surprise really because the march sunshine is strengthening and there was barely any cloud to block that sunshine out during the course of friday. it will be a similar story through the day ahead. with the high pressure sitting around for the foreseeable, certainly through the weekend

and beyond, isuspect we will see higher than 17.5 celsius. fairly brisk wind around at least for the first part of the weekend there may well be 1—2 showers by sunday. but for the most part, because that high—pressure is across the uk it will stay dry and fine and as the winds start to weaken into three—week temperatures will rise, it'll be really quite warm and feel quite warm in that strengthening march sunshine. a chilly start on saturday and some patchy fog around. the frost is more likely across northern and eastern areas, not as widespread as friday morning and the fog won't be but they will be pockets around potentially, we've seen some in northern island northern and eastern island a few other spots as well. otherwise, it looks like a sunny day on saturday but a fairly brisk wind. breezier certainly than we saw during friday. that wind will be strong and gusty particularly across western areas but coming in off the north sea as well it will have an effect on temperatures there. it's also coinciding with spring tides or with the potential overtopping of the waves but strong

against the winds across the south west peninsula. but as i say, for many westernern areas and the south as well gusting at 30—a0 mph. coming off the north sea at this time of year many will see temperatures at their lowest. that will obviously hold the temperature right on the coast down at 15—16 as we saw friday but we could actually see 18 in the northwest highlands with some shelter here from the breeze. clearly, we may get about 17.5 during the day ahead. more likely saturday i think then sunday. sunday looks like it will be slightly cooler that's because will have more cloud. a colder start, more widespread falls sunday morning and morphed fog around. we got back to clear. the winds are coming in from the esop actually rose bring in the west to enact risk of showers and more clout into southern and eastern areas and work hard into the west. with more cloud around it may well be a little cooler than saturday.
