I think hopefully as you're getting older you're getting parts that require more preparation, and by that I just mean - I don't know, usually the older you get you get characters with more responsibility. Each one is different, there are certain movies that when the guy starts you pretty much come with that character on page one and then you see their growth, whereas other guys a lot has happened before that movie starts and you have to come in with something.

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.

I just really enjoyed all that kind of responsibility, I loved the fact that many people cared. I was doing 4 hours of boxing, 2 hours of weights, an hours of accent and dialect training, I just enjoyed having to do all that for this character [ Vinnie Paz in Bleed for This].

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 think when you're looking for scripts or for characters around your own age, a lot of the times they don't have the kind of responsibility that is usually seen in parts that are older for you.

I grew up in a very small town in Florida, like, 7,000 people.

Living in somebody else's pain for an actor man, it's actually nice when you get to feel that kind of emotion. That's what I like.
