Actress Emma Watson will star in the next Harry Potter movie, despite rumours she was leaving the franchise The actress, who has played Harry's sidekick Hermione in the last five films, has played down suggestions she wanted to leave the much loved series - insisting she would do them for free. Earlier this year (07), her co-star Rupert Grint fuelled reports she was quitting, by saying, "Emma doesn't want to do it any more. She's tired of being known as 'that girl from Harry Potter'." However, she hit back saying, "I definitely intend to do (another Harry Potter movie). "I would do Harry Potter for nothing. It's not really anything to do with the money."
