Michael Caine is so happy. Happy and healthy. I think he enjoys life. I think he's 82 now, and I have no clue if I'll be working at that age.

It's a constant learning process - not just what you need to learn for the character or as far as good actors - but as an actor, there's no limit. Every time now, you're learning so, I think that's a good thing though.

For me, playing a really bad character is about figuring out what brought the person to where we need him.

I remember going to the theatre when I was little and the lights going down and just getting really scared about what was going to happen up there.

I know that part of why I was excited to do this was the sense of play and childlike wonder and the spirit that's in the Daniels' work. I think we're tracking some issues that are actually quite sad or lonely but I think in a joyful, creative way. So I like that balance. I think singing in the woods, the music and spirit of that - there's something very pure about the film [Swiss Army Man].

I approach every role from scratch.

Being actors is a strange job. To try to go live that out, it's a very strange thing to want to do when you step back and think about it.
