I have always been a great fan of Peter Chan and many other great directors who specialize in anything outside of action.

I always used to wonder why American actors were getting fat, then I made a U.S. movie. I'm seeing all the food every day, and there's lots of waiting around because making an American movie is very slow.

The main reason I like UFC is not just the martial arts aspect, but it's about one person against the other person. It's about being able to test yourself with the truth.

For me, shooting, editing, and scoring rely on rhythm.

A lot of Chinese martial arts films were based on Chinese martial arts novels. And these novels created a world of putting history, calligraphy, and martial arts into one.

Personally, I prefer contemporary films, but the market calls for more period choices, especially since China opened up a cinema market in Hong Kong. There's a lot of restriction for contemporary films simply because of subject matter.

If you're playing a cop in a modern film, you don't have to walk with your spine straight up and bow before a fight. There's a lot of free form of expressing yourself as an actor.
