I'm not a method actor but it certainly does help to have that kind of dedication. I treated my preparation like I was in the military. I didn't go out ever. I went out for drinks probably twice in five months. I lived very monastically.

When I came on to Jack Reacher, I had just taken my girlfriend on vacation and ate everything I could. I put on about 15 pounds, so when I met [the Jack Reacher team] I was clocking in at about 180. They looked at me and were like, "You're just gonna lose five pounds, we're gonna keep you skinny".

Obviously I was talking to my parents and my girlfriend all the time, but it's one thing to finally be in the same room and get to be with each other and just hang out.

For some roles, like when I was doing Bent, that was harder and I didn't find that helpful because I was so calorie deprived, my brain wasn't getting food. I would end up not being as focused or as clearheaded as I would have liked to be during the run of the performances. I would lose those quality impulses that you lean on when you're acting because of malnutrition. basically. But I looked skinny.

You're working so hard and so many hours, you simply don't get to visit with everybody when you're gone for five months. That's part of the trade in we make with this career. You don't get to maintain the intimacy you would like to.One of the big things I was doing was working on reestablishing that.

I read as many books about the psychology of a psychopath as I could and I researched what exactly happens to soldiers.

I'm obsessive about my job and I want it to be as great as it can possibly be, especially right now in these early parts of my career.
