If I had to choose, I would never take my shirt off again in a movie, but I guess that's not very realistic. I certainly won't be asking to do it, though.

Boxing is so loose and flowy, and martial arts is more stiff, and about strength and structure.

The actual getting into the gym and working out process was easier, but the eating was harder. I had to eat every two hours. At one point, my trainer said, 'Put anything in your mouth. Go to McDonald's, get the biggest shake possible. I just need to get calories in you.' Because my body fat at the time was only, like, seven and a half percent.

I was in the gym five days a week, two hours a day. At one point, I was going seven days straight. I had put on a lot of weight, and then I started losing it drastically, so I was worried. It turned out I was overworking myself. My trainer told me that I couldn't break a sweat, because I was burning more calories than I was putting on.

I guess winning an Oscar is the ultimate dream. A lot of amazing actors go their whole career without even being nominated. So that would definitely be a goal to reach. It's a difficult one, but I'm aiming for it!

I've always been really active. I grew up playing sports, so I'm always shooting hoops or throwing the football with my friends. I'm super-active in that sense.

At one point I had to shove as much food in my body as possible to pack on calories. My trainer wanted me to do six meals a day and not go two hours without eating. If I would cheat on eating one day, I could tell - I'd drop a few pounds.
