<P> Wonka then invites Charlie to come live and work in the factory with him, and reveals that the purpose of the Golden Tickets and the tour was to make the "least rotten" child the heir of the factory itself . The only catch is that Charlie must leave his family behind, because Wonka believes family is a hindrance while a chocolatier needed creative freedom--a philosophy Wonka developed due to his dentist father, Dr. Wilbur Wonka (Christopher Lee), denying his son candy because of the potential risk to his teeth . After sneaking over a piece of candy, Wonka was instantly hooked, and ran away to follow his dreams . When he returned, both his father and their house were gone . </P> <P> As his family is the most important thing in his life, Charlie refuses Wonka's offer . Charlie and his family are living contently a while later, however Wonka is too depressed to make candy the way he used to, causing his candy to sell poorly and his company to decline . He turns to Charlie for advice . Charlie decides to help Wonka confront and reconcile with his estranged father; Wonka finally realizes the value of family, while his father learns to accept his son for who he is, and not what he does . In the end, Wonka finally allows Charlie's family to move into the factory, Charlie has the chocolate factory, and Wonka has patched up with his family . </P> <Ul> <Li> Johnny Depp as Willy Wonka <Ul> <Li> Blair Dunlop as Young Willy Wonka </Li> </Ul> </Li> <Li> Freddie Highmore as Charlie Bucket </Li> <Li> David Kelly as Grandpa Joe </Li> <Li> Helena Bonham Carter as Mrs. Bucket </Li> <Li> Noah Taylor as Mr. Bucket </Li> <Li> Missi Pyle as Mrs. Beauregarde </Li> <Li> James Fox as Mr. Salt </Li> <Li> Adam Godley as Mr. Teavee </Li> <Li> Franziska Troegner as Mrs. Gloop </Li> <Li> Christopher Lee as Dr. Wilbur Wonka </Li> <Li> Deep Roy as Oompa - Loompas (with vocal work by Danny Elfman) </Li> <Li> AnnaSophia Robb as Violet Beauregarde </Li> <Li> Philip Wiegratz as Augustus Gloop </Li> <Li> Julia Winter as Veruca Salt </Li> <Li> Jordan Fry as Mike Teavee </Li> <Li> Liz Smith as Grandma Georgina </Li> <Li> Eileen Essell as Grandma Josephine </Li> <Li> David Morris as Grandpa George </Li> <Li> Geoffrey Holder as the Narrator </Li> </Ul> <Li> Johnny Depp as Willy Wonka <Ul> <Li> Blair Dunlop as Young Willy Wonka </Li> </Ul> </Li>
