When you play a lead role, you're in pretty much every scene. It's incredibly tiring. You really have to disappear into the film because you have no time to do anything else. You are either awake and playing the character, or you are trying to catch up on sleep.
I don't agree with boarding school. It's not something that I would do with my children, but I think it's something that kind of exists in England in a traditional way, and you do form very close relationships with the girls you go to school with. But it is a strange thing to live in an environment which is solely female.
