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.

I enjoy the physicality a little more, with Vinnie Paz [in Bleed for This] that was the most prep I've ever had to do for a film, that was a legit like 7 months of diet and working out. And then I was able to do like an accent, I was able to change myself physically, I was able to do a lot of the things that I'd always looked at actors and admired when they did that. So I was excited to do that.

Just go to a bar, watch football - that's fun to me because I've not gotten to see anything because I've been travelling so much. Playing some shuffleboard and some pool and darts. I like kind of dive-y bars.

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 feel like my body doesn't judge the hours, you know? It doesn't care if it's daytime or nighttime.

I've played drums since I was 15. My sisters and I all played instruments. I kind of started with piano and then I actually played saxophone with a jazz band in middle school. So, any knowledge I had of jazz music was from playing alto-sax back then.

My second grade teacher told me I would never graduate high school. That I was going to be a juvenile delinquent.
