How do you meet the cast of Harry Potter?

Answer 1

I suppose that the only way to meet them would be if you won a competition or if you were involved in the film.And it is very unlikely to meet them until after finishing filming harry potter.

My friends knows someone who knows Rupert Grint, so you could just ask around the family or something.

You could try to go to a premier and you might be able to get a signed autograph, some of the cast talk to people when they are signing.

EDIT: go to a premier or a film festival where you know the cast is meeting. bug them about it. walking around known places of work is a little creepy but it works. its how tmz works. few of them host contests. or get famous yourself.
