Where will they go?

I was thinking about the upcoming Harry Potter movie, The Half Blood Prince, and thought about reading the book again. The Half Blood Prince and The Deathly Hallows are the only two books that I have not read more than one time. Anyway, I started thinking about the new movie, out in November, and then started wondering about the actors. The kid actors, more specifically. Some of the adult actors, like Alan Rickman (Snape) already have extablished carreers and should be able to find more work. However, after seven movies, being cast in such huge and popular roles, what will these kid actors do with their lives? I'm sure that none of them will be wanting for money, but will they want to retire in their early 20s? Can you see Daniel Radcliffe as any other character than Harry Potter? Or Emma Watson as anyone other than Hermione Granger? Will they be doomed to the child actor curse of falling into depression and a life of drigs after ther carreers are over, like so many child actors before them? Look at the Coreys, Haim and Feldman. What have they done since their childhood glory days other than get in trouble or do bad reality TV? Will Harry and Ron show up in ten years in some mansion surrounded by cameras and young girls trying to win a date with a has been? Will Hermione end up gracing the pages of adult magazines in order to make a buck because no movie makers will put up with her poofy hair and snotty attitude? I guess there are exceptions to the rule. Alyssa Milano was a child star, appearing in Who's the Boss and some movies, and she ended up making a mint with Charmed. But really, how many child actors are out there that made it just as big in their adult careers? I am trying to think of more child star examples, but I guess my point is made by the fact that I can't.
