really am magic in real life. >> and it's coming to an end. >> i'm grateful to be a part. i've loved every day of it. >> never seen before footage of the making of voldemort. behind the scene secrets finally revealed and an exclusive clip of the final harry potter movie you will not see anywhere else. daniel radcliffe, emma watson, rupert grint, helena bonham carter, robbie coltrane, yams and oliver fleps and tom felton, they're all here on the larry king special harry potter, the final chapter. >> cut, great work guys. >> i'm coming to you tonight from harry potter the exhibition here in new york city. you might recognize harry's dorm room. it's right behind me. you know, whether you're a muggal, 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. rolling'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 alone have made some $6 billion. tonight you'll hear secrets from the set. you'll see how the wizards world was brought to the big screen. we'll even show you an exclusive never before seen clip of the final movie just days before it opens. but first a look back at how it all began. >> harry, be safe, be strong. >> harry potter, the boy who lived faces his biggest challenge yet. >> only i can live forever. >> a final showdown with the dark lord valentine da mort. an epic battle ten years in the making. >> the last harry potter. how does that feel? >> you know, very, very strange considering we've done it for ten years. it's also a wonderful feeling of achievement and particularly you know, i'm very, very proud of this last film and it's the best out of all of them i think. and yeah, i'm very, very excited. >> also excited? well, the millions of harry potter fans around the world who have been waiting years for this finale. >> from what i could see just shooting it, i knew it was -- it's pretty epic. it's as -- i think we do it justice. i definitely -- yeah. i do. >> now, join me, harry and confront your fate. >> voldemort is kind of rising again and it's disturbing to be losing characters that we've known since the first book and it's, yeah, i think it's going to be shocking just 0 see the cast kind of collapse to this kind of burning piles of rubble. >> come on. let's finish the story where we started together. >> harry potter and the deathly hallows," part 2 is sure to be the biggest movie event of the summer and will give fans the ending they've been waiting to see since we first met the young wizard in 2001's harry potter and the sourcer's stone". it was tense years ago for the very first time we were able to see the world that until then was only imagined in books. >> plenty of courage i see. not a bad mind either. there's talent. >> up. get up. >> we laid eyes on harry potter. orphan who was made to live in the cup board under the stairs by his aunt and uncle. >> there's no such thing as magic. >> tormented by his cousin. feeling isolated and alone, who found out if he was not only a wiz wizard, but the most famous wizard of all. we were also introduced to his two best friends. >> oh, are you doing magic? >> the book smart know it all hermione granger and harry's sidekick ron. the books and the seven movies so far have made stars out of the three then unknown child actors. daniel radcliffe, emma watson, and ruppert 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. >> the first film was an instant hit forewarner brothers which like cnn is owned by time warner, but 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 deem dreeped up by an unlikely author, j.k. rowling who 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, how an idea came about? do you remember though the creation of this concept? >> yeah, it came to me on a train going from manchester to london and it came very suddenly. >> what came? >> the idea for this boy who didn't know what he was. until he was 11 and then he got this invitation to go off to wizard school. i had this very physical pons to the idea. i was so excited. >> the first book was released in 1997, marketed as a simple children's book by a first-time author, many people, including rowling hearse did not have high hopes for it. >> i thought i was writing quite an obscure book, that if it ever got published would maybe have a handful devoted. i think it is a book for obsessives. i thought maybe a few people would like it a lot. i never expected to have broad appeal. >> roling who was turned down by several publishers after she wrote the first book has become one of the richest woman in the world, so successful she's reported bypassed even the queen in wealth. her story spawned seven best selling novels which have 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 a cause for celebration for fans who lined up days in advance to be the first to walk out with the latest sorry. but in 2007, when rowling released the final chapter of the series, harry pot ter and the deathly hallows," we knew it would eventually come to this. >> the boy who live d come to die. >> 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. >> why? >> i think it's the most exciting. i think it's the most direct. i think we did so well in part, by setting up all the 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 the films and the action-packed adventure exciting side. i mean, 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. >>. >> coming up, an exclusive trip from the final harry potter film that you won't see anywhere else. plus, we'll slow you how raef fines went from this to this. but next, daniel radcliffe reveals what happened on the last day of filming. >> i kind of went like a child on that last day. >> when this larry king special harry potter the final chapter, returns. in here, the planned combination of at&t and t-mobile would deliver our next generation mobile broadband experience to 55 million more americans, many in small towns and rural communities, giving them a new choice. we'll deliver better service, with thousands of new cell sites... for greater access to all the things you want, whenever you want them. it's the at&t network... and what's possible in here is almost impossible to say. fiber one. uh, forgot jack's cereal.

>> i was in the bath, and my dad got the phone call downstairs and came in and said, you've got the part. i was just very, very happy. >> how old were you? >> i was 11. i think i just turned 11. i had no idea what the implications were but knew that that probably meant i bought myself a half hour extra before i had to go to bed that night. >> the implications were that radcliffe's life was about to change forever. did you have a normal boyhood? >> it's very hard to say. i mean, no, i guess is the short 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. that's kind of really -- i was also 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. >> you didn't. can you explain that? >> kids are not supposed to be famous at 11. >> no, they're not. i think what i put it down to is the fact that the -- i think it's very different doing it in england than it is doing it in america. i think when you do it over here, you're treated as a star first and a child second. whereas in england, i think it's the other way around. you're treated as a child first and then you're also an actor in these films. but i don't think anyone panders to it possibly as much in england as they do in america. thankfully i have not gone massively off the rails. >> have you enjoyed it? >> oh, yeah, immensely, absolutely. i mean, while there have been moments obviously i'd be lying if i said every single day was fantastic, but, you know, generally speaking, i just had the best time. i got to work with my best friends every day. >> do you like harry? >> yes, i do, very, very much. >> anything you don't like about him? >> yes, of course. he's kind of arrogant and pretty selfish at times. not so much in the later films and, also, i think there's often a little bit of the smell of burning martyr about harry. he occasionally, i think, likes to -- the fact that it's all on him and i mean, i think there's a line where he says he eames to relish his fame. while i think that's obviously true, he does have a hero complex that he thinks he always has to be the hero, which i suffer from myself sometimes. >> really? >> i think so, yes. >> not wanting to be typecast forever as harry potter, radcliffe began branching out. in 2008 he made his broadway debut in a controversial show, "equus" appearing naked on stage. today he stars in the revival of "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 the dancing and singing, yeah, it's something completely different. i've got the energy to do it at this age. i might as well do it. it's also -- i do think there's -- as an actor, i don't think you'll ever work ha much harder than doing a broadway show, particularly a musical eight times a week. yeah, i like working hard. that's the other thing that potter has instilled in me is a work ethic, that i love to work. >> how have you kept a balance through all of this? >> i think the most important thing for me to remember is that it doesn't matter who would have got this part. they would be receiving this kind of attention and this much -- when you step out of the car at a premiere and you get hit by that wall of noise and screaming, it's reimportant for me to remember that they would be screaming for somebody else had he got the part. it's not about me. it's about the franchise and the character. that, i kind of have to think about a lot to keep it in perspective and stop myself getting big headed. coming up next, behind the scenes exclusives, special effect wizards will show us never-before-scene footage of the making of lord voldemort. plus, an exclusive first look at a scene from "harry potter and the deathly hal lows:part 2" on a larry king special "harry potter, the final chapter." goodnight, stuffy. goodnight, outdated. goodnight old luxury and all of your wares. goodnight bygones everywhere.
