Because I'm short and slim, I can identify with somebody who's an unlikely fit for something and desperately wants to be part of it.
Both of my parents have been actors; there were a lot of show tunes on in the car all of the time. I grew up with that.
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!
I could never do stand-up because it's that thing of having to get up on stage. And out of every 10 jokes you tell, nine of them have to get a really good response.
