I'm a serial monogamist. I'm not one of those people that can date loads of people at the same time, it's all too complicated.

I'm always amazed at the way some actors' behaviour is truly disgusting. That's one thing that will never happen on one of my sets if I ever direct.

We sing a lot of the soundtrack in this film [Swiss Army Man] - me and Paul Dano - and on the last day of filming we had to just get into the back of our sound mixer's van and record a really crappy, rough version of the singing then. For some reason that was one of the most fun days.

I would say I was challenging the system quite. But I like to think that if the choices I make are slightly unexpected or challenging to people, then that is good. We are definitely three fairly like-minded people in terms of what we value in scripts and in storytelling.

I really enjoy working physically.

I'm possibly a very morbid person but I think about death a lot. I don't know if it's maybe from being on films that's often playing Harry [Potter] or I just think it's a natural thing that I have. It's something that I think about just because it's fascinating in a very alien kind of way.

Normally I sit there in the films really hating watching myself. Loving watching the films, hating watching myself.
