I think one of my favorite things to do is just lock myself up in a small room and listen to music and watch films for a day. Also I just like seeing my friends. We have pizza parties which means I get four friends round, we eat a pizza and we're really lazy and we play PlayStation.

We would choreograph [ with Paul Dano] before each scene [in Swiss Army Man] and very quickly got to a place where we could improvise physically in scene and know that the other person would respond in character appropriately. So that [dynamic] was a lot of fun.

I take things in better when I'm allowed to talk, and respond, and engage and move around a bit.

Go boldly and honestly through the world. Learn to love the fact that there is nobody else quite like you.

Acting is really instinctual and I think you can overanalyse what you're doing. A lot of it has to be based on instinct.

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'm somebody who is very, very proud to have been a part of the British film industry all my life and to have kind of been involved with a very important piece of British film history.
