They don't mind getting punched in the face and, more importantly, they don't mind punching other people in the face. I'm just about the movies; I enjoy the dexterity of actors in action movies and the choreography side of things. You've just got to be a different person to be a professional fighter. I train with professional fighters so I know what it takes. It's a very difficult profession, probably harder then the acting profession.

I put so much pressure on myself to raise the bar with each and every project. I treat it like every film is my last, and I make sure I pour everything I have into every film I make because if I'm not trying to improve, someone else will.

Whenever you're looking at new ways to get in shape, first you have to decide what you want. Do you want a more muscular look, or do you want to slim down and appear more toned and ripped? I adapt my training and diet with each role I do, depending on the image I want to convey.

It was weird working with all of them - Stallone, Schwarzenegger, Bruce Willis, Chuck Norris. There's a sequence in the movie where myself and Jean-Claude Van Damme are running through this airport and there's this silhouette behind this big screen - it smashes, and there you see Schwarzenegger, Stallone, and Bruce Willis all firing their weapons at me and Jean-Claude. It's kind of surreal when you think about it, the three '80s icons of action movies, unloading as many bullets as they could at us. It's pretty crazy.

I did martial arts since I was 10 years old, and I've got as much love for the movies as I have for martial arts, so when I was 18 years old, I started studying performing arts with the eye of getting into the film industry and went to drama school after that.

I do find violence entertaining, but that doesn't make me a bad person. I grew up watching all these action films when I was a kid. My dad would bring back 'Rambo' and whatever, and we'd watch it together. It's not affected me in any way other than I just appreciate the entertainment value of violence on film.

The genre of '80s action movies, I think, changed really when The Matrix came out and Keanu Reeves was able to perform kung fu. Then you had Matt Damon in the Bourne films, doing a great job. So it's different now, they can train actors to do their own fights convincingly on screen, so those guys aren't needed anymore. But I think everything goes around in circles; people still do want to see the guys that can do stuff for real, that's why The Expendables is so popular. I think it will come back again.
