I was in good shape from Divergent. Damien Chazelle, the director of Whiplash told me, 'Stop Working Out! Don't go outside!' He wanted me pale and doughy. This is the first movie where I shut myself off from the world. It was, by far, the hardest thing I've ever done.

For me, as far as friendship goes, I think you truly get out of it, what you put into it.

I grew up middle class, my best friends to this day are construction workers or military or whatever it is.

First play I ever did was 'Footloose.' I played the part of Willard when I was 16. I think I wore my drama teacher's jeans and her belt - that's how small I was. I know a lot of Willard's back story from the musical that's not explored in the film. Like he's got this whole relationship with his mama, and he sings this song "Mama Says".

I've played drums in bands since I was 16.

For me, the greatest kind of success that I've had on a particular project or in exploring a role does come through collaboration. I wouldn't want to do a movie where everything I do the director just says, "Good job" and I'm under directed.

Honestly, I'm not a big movie buff in general. The only movies I own is probably the 'Indiana Jones' trilogy.
