When you're in the position I'm in, you have two options: you can either shut yourself off from everybody, from the world, and not live a full life. Or you welcome everybody into your life and occasionally somebody will try to take advantage.

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

It was a lot of fun to play a character [in Swiss Army Man] with no inhibitions, and with no knowledge of the world, and who comes into the world kind of like a blank slate. It means there's no template or blueprint for how you need to play certain scenes.

The real challenge of acting for me, I suppose, is just getting to know a character very, very well and just applying what I know about them to every single scene. That's what it can be broken down to.

I'm possibly a very morbid person but I think about death a lot.

I mean I've seen 3D films so far and I think it's a long way to go before they replace actors. It's a funny thing with 3D, I haven't quite got it yet. Yet.

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!
