I feel like a lot of the films I do, part of the reason I like doing them is I'm not 100 percent sure what it's going to be. It's exciting. I read an equal amount of very generic scripts, and you kind of know exactly what those are and that doesn't whet my appetite. I already know what it is or I already know what the character is. It's just a lot harder to get interested.

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

You try to get to know your character as best as you can before you start filming - whats written and not written.

I think there was a lot of working out the arc of how Manny [Daniel Radcliffe] talks. Scene to scene [in the Swiss army Man], if I would start talking a little too well, they would come in and say like, "Hey, you need to [dial back] your ability to speak" - things like that.

If you could call me buff, my version of buff was when I finished that film [Swiss Army Man].

On set, the playground for the character, how much it takes varies. Is it like ballet, is it like jazz? The content always lends itself to the form, and it's really not mathematics.

Reading the script [Insane Farting Corpse], by page two or three, I felt that way. I thought, I'm in. It was so beautiful and insane and funny and I wanted to see it happen.
