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

I guess I'm pretty lucky because in childhood I studied so many martial arts styles and I never stopped researching them, my body is very adjustable and I can turn into different expressions with my body.

As an action director I always try to bring something fresh and new.

It takes years of building that experience as a filmmaker, as well as physically. You have to have a high level understanding of martial arts.

Martial art is a form of expression, an expression from your inner self to your hands and legs.

I don't make comparisons between any movies. I compare characters. All my actions, performances, all my films, they are driven by the characteristic. If I'm playing a cop, then I give him a particular style - I may not know that style, but as an actor I have to be responsible to do your homework and do your research and training and stuff like that.

I think a lot of people don't realize that martial arts are just an expression like anything else. It's just that most people are not trained to punch or kick, but you can walk or run or dance, which is also part of expression.
