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

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.

I gained a lot of confidence after 'IP Man' as being a true actor. I went on to tackle what it is an actor is supposed to do before a film. Do a lot of research, get into the character. That's what I did with 'Dragon.'

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.

I spent a couple of years doing American films. I did a few.

For me, the challenge of a period film is that, unlike a contemporary film where the character can be very free-form when it comes to the acting, there's a burden to acting in a period film because you have to stay within the character's historical background and the gestures of certain periods.

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.
