not a chance. >> reporter: could they change the paradigm of the ugly divorce? >> hollywood will learn nothing from this. >> while we love each other very much, we will remain separate. we are, however, and always will be a family. and in many ways we are closer than we have ever been. >> listen to this song "magic" from coldplay's brand-new album. ♪ i still call it magic ♪ when i'm next to you >> that's unconscious coupling right there. maybe gwyneth has engineered the perfect divorce after all. half of us will love her for it. half of us will hate her . i'm nick watt for "nightline" in los angeles. >> uncoupling. thank you, nick for that report. next, it's cops versus motorcyclists and we're with them for the epic showdown.

let's see what you got. rv -- covered. why would you pay for a hotel? i never do. motorcycles -- check. atv. i ride those. do you? no. boat. ahoy, mateys. house? hello, dear. hello. hello. van with airbrushed fire-breathing dragons. ah! check. thank you. the more you bundle, the more you save. now, that's progressive. eating healthier,tion by drinking plenty of water, but still not getting relief? try dulcolax laxative tablets. dulcolax is comfort-coated for gentle, over-night relief. dulcolax. predictable over-night relief you can count on. but sometimes, i still struggled to get going, even get through the day. so i was honest with my doctor. i told him i'd been feeling stuck for a long time. he said that for some people, an antidepressant alone only helps so much

and suggested we add abilify (aripiprazole). he said that by taking both, some people had symptom improvement as early as 1 to 2 weeks. i wish i'd talked to my doctor sooner. [ female announcer ] abilify is not for everyone. call your doctor if your depression worsens or you have unusual changes in behavior, or thoughts of suicide. antidepressants can increase these in children, teens and young adults. elderly dementia patients taking abilify have an increased risk of death or stroke. call your doctor if you have high fever, stiff muscles and confusion to address a possible life-threatening condition. or if you have uncontrollable muscle movements, as these could become permanent. high blood sugar has been reported with abilify and medicines like it and in extreme cases can lead to coma or death. other risks include increased cholesterol, weight gain, decreases in white blood cells, which can be serious, dizziness on standing, seizures, trouble swallowing and impaired judgment or motor skills. [ terri ] since adding abilify, i feel better. abilify and my antidepressant make a pretty good team. [ female announcer ] ask your doctor about a free trial of abilify and go to addabilify.com.

>> we know something is going to happen on saturday. it's inevitable, man. until you ride with a group of 400 or 500 bikes, 1,000 bikes or whatever and you ride through a town, there's nobody out there in their right mind that's going to try to challenge you. >> every city has its landmark. in charleston, south carolina, it's the ravanel bridge. chad plans to lead hundreds of bikers to block it, stop traffic, and take it over as a private playground for private stubt biking. they call it the chuck town shutdown. casting a shadow over the plans -- this video which made national news. a stunt ride on a new york city highway. a group of bikers blocked traffic. an suv pinned in the group makes contact with the biker. the group reacts, surrounding the vehicle.

yes. >> the highway is not a place to do a stunt. >> law enforcement plans to show up in force and stop the shutdown. do you anticipate conflict? >> no, ma'am. >> they've got to understand what our job is. and it's law enforcement. and all it takes is one little tiny thing and we've got a ten-car pile-up. >> reporter: captain woods has been riding motorcycle seasons he was 12 years old. he spent his entire career in law enforcement. >> this is a unique situation. >> reporter: you're prepared for the worst? >> we are. >> what we're guarding against is them blocking those intersections so they can go through without stopping. >> on the mornings of the shutdown, some of the bikers are worry about getting arrested.

>> i don't want to call out of work on monday. >> i got money just in case i need to get bailed out. >> jimmy: the turnout is smaller than last year, but the die-hards show up. >> this piece of machine right here. everything that i live for, erg that i die for. this is my life. >> i have ptsd. my bike is what teep kooep kee levelheaded. >> anybody makes any contact, get on the radio and let us know you've got a group so we can get other people there quicker. >> chad switches the start location for the shutdown. >> no, no, that's not where we're going. >> some things we're hearing is that the overall thing is d canceled. some say there's 180 riders. you just don't know. >> reporter: you set up decoys online. >> you got to.

concentration. >> if they block traffic, you all take care of that. >> the police can't arrest them for simply wanting to shut down the bridge. they start pulling over bikers for any traffic violations. >> what happened? and as the police begin to infiltrate, the ride breaks up into smaller groups. the brook led by chad are the first to reach the highway. >> the cops think they're ahead of the game. they think they know where we're going and what we're doing. we're just rerouting ourself right now, that's all. >> now catching up to the front group.

>> nothing is more nerve wracking than seeing 50 motorcycles in your rear-view mirror. >> half an hour into the ride, the bikers have regrouped and can see the bridge. >> they've moved to the onramp for the ravenel bridge. >> spread out a little bit. >> all the lanes are blocked. >> as the bikers begin amassing on the bridge, law enforcement moves to the front. suddenly police converge on the lead biker with an exposed weapon.

>> they're surrounding me. all drew their guns on me. >> keep your [ bleep ] hands on the bike! >> [ bleep ] you [ bleep ]. >> it's nerve wracking. you've got a lot of motorcycles. a lot of thing goings on. >> how's your blood pressure? >> good, i'm legal. that's why i stopped. if i wasn't legal, i wouldn't have stopped. >> but the pullover stops the momentum. it effectively puts an end to the shutdown. the police escort the bikers to their stunt lot. >> we didn't accomplish what we really wanted to. we really wanted to have some fun on the street. but they came with a really strong opposing force. >> my goal was for no one to get injuried. nobody hurt, no crashes. we got all those motorcycles over here without that happening. so i'm very pleased about that.

too much from the bible. and some muslim countries have even banned it. >> we've had trouble for over a year now of very harsh criticism from a bunch of people, just an assumption of what it could be or how bad it could be. which, you know, i think quite frankly is bordering on absolute stupidity. >> noah cost an estimated $125 million. but producers expect to see the profits flooding in. >> a great flood is coming. >> it's the priciest in a recent of big biblical films including "son of god" and "exodus" with christian bale due out later this year. i guess when you bet on the bible, you're betting big. we're all on line at abcnews.com. good night.
