As an actor, it's all about whether you can sell the emotion on your face... that desperation, the panic and rage that comes with combat. The emotion of combat is important to me. I mean, you feel almost sick if you see a real fight where someone is getting badly beaten up. You can get emotionally involved in combat that has nothing to do with you in real-life, let alone if you are actually in it... or it's someone you know, and so you should have those same feelings on film.

Even when you spar for real and fight with full contact in training, you get hurt or you hurt someone and you see them trying to fight back. I want to inject as much reality as possible into fight scenes, even if some of the moves are slightly larger than life, if the emotion is there you'll then still be able to buy it. I recall seeing some films where people perform an acrobatic flip mid-fight and land with graceful precision and it's almost like watching Zorro... it's almost whimsical but you're no longer engaged.

When I started martial arts... Bruce Lee is obviously the top dog and Jackie Chan is a legend. But for a lot of westerners it was Van Damme. He was the first person you saw that made you realise you didn't need to be Asian or Oriental to do that stuff.

I don't attract violence because of my stature and because of my lifestyle choices. I don't like to go out and be out of control or intoxicated because you could be the toughest guy in the world and still be vulnerable if you're not in control of yourself. And I don't like to go to place that are unnecessarily confrontational or dangerous. But I used to work in a pub and had to help the doorman fight off a load of people at one time. So, I've seen enough.

Action is cool but it's all down to the director's interpretation at the end of the day, so you have to serve his visions and do what you can. So, you do your job to the best of your ability, you perform the fight and then it's out of your hands. It's then down to the director or the producer. You can give your opinion but often it's not heard. Actors have their riders and all kinds of contract terms and one of my big ones as I continue to make a name for myself as a top action guy is that I design my own action in films and oversee the edit.

In films, people sometimes forget and concentrate on the fight itself, which is great, but the 15 minutes that come beforehand are equally as breathtaking.

With action in Hollywood, a choreographer will be hired to design an amazing fight, with all these cool little narrative bits, such as a fighter having to perform a certain move because he's been injured and can only move that way, but it can all get lost in translation because the director then does what he wants with it and then passes it on to the editor, who does his interpretation of the fight. It becomes almost like Chinese whispers, so sometimes the end fight you see on film is so different to how it was conceived and looked on the day.
