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'll be honest, I never saw myself making a ninja movie, never entertained the idea. I think ninja films can be quite cheesy unless you do them in feudal Japan.

When I was ten years old, my dad and brother did JUDO so I went along because I felt like I was missing out. They eventually gave up and I continued, then moved into Tae Kwon Do, kickboxing and various other martial arts. I did lots of different things, but mostly things like Wushu, Jeet Kune Do, Krav Maga and stuff like that.

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.

I'm good when I've got a bit of an edge, like the Clint Eastwood type of archetypal character. The tough guy that doesn't say a lot.

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.

My first break was in a Hong Kong movie that I shot in China - I was going out there and working as a western stunt man, if you like, but at the same time in England I was working in daytime soap stuff. Eventually I put the two together.
