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 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.

I try to update my arsenal constantly. Learning different martial arts since childhood. To understand what's out there. To really be in tune.

In Hong Kong, particularly, we craft this art for decades. The action choreographer actually is the action director. He takes over and he choreographs with - by himself or with his team, and place the camera where he feels cinematic effect to bring out that choreography.

A period film, where you, for example, where you have a traditional wardrobes, you are bound to act a certain way. But in a modern film, a lot of body gesture.

Still, as much as I wish Ballistic Kiss could be a better film, the recognition it gained from critics and at festivals speaks for itself.

There is also a strong following among the urbanites on the East Coast when it comes to martial arts films.
