The stories I'm interested in are challenging ones, and maybe that requires a little bit more of you. I love my job and I want to earn the right to do it every single day.
It's important to say that the more challenging a scene is, in a way, the more fun it is because the more of my job I get to do.
My taste in the films I've taken as an actor is similar to what I'd do a director or writer: all quite odd, challenging stuff, slightly off-the-wall.
I see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!
