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".

[Jack Reacher] is the longest I'd ever shot anything - and let's be clear, this is my first studio feature film - so there was a huge learning curve.

It's pretty tough on your loved ones to try to get back into a rhythm, especially when all you want to do is do nothing.

I only had a three-week break from the beginning of Bent, so I went from one thing to the next. I got back [from shooting Jack Reacher] and there was a sense of, "Oh my God, what do I do now?" I don't have personal trainers around me all the time, I'm not on a meal plan, which I had been on for almost a year straight. There was a lot of sleeping.

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.

The guy [Tom Cruise] is a machine.

My character is called The Hunter. He's the main antagonist in the movie. In a nutshell, he's a slightly deranged natural born killer who's weirdly determined to succeed at his job, whatever his employment is. He's a mercenary and there's a high body count for him in this film [Never Go Back].
