I have every sympathy for writers. It's a mystery to me what they do. I can edit. I can cross out and say, 'I'm not saying that' or, 'How about we move this to here? Wouldn't that make that bit of the story better?' But where any of it comes from is beyond me. I will never write a play or a novel.
Acting is about giving something away, handing yourself over to whatever role you are asked to play. I'm not hiding or escaping or seeking anonymity. I reserve the right not to have a rubber stamp on my forehead saying this is who I am. Because who I am gets in the way of people looking innocently at the parts I play.
I never talk about 'Harry Potter' because I think that would rob children of something that's private to them. I think too many things get explained, so I hate talking about it.
