I think, if allowed, 3D is a new film language. I can have more adventure exploring a new media, that's very exciting. 2D we know most of it, things haven't changed for decades; it's the same principles, so 3D's more exciting.

I like to think I'm un-categorisable.

Making a martial arts film in English to me is the same as John Wayne speaking Chinese in a western.

Directing, I get all kinds of inspiration. It's working with people. It's a lot more fun.

I don't like to deal with studios. I don't like to have conversations with executives. I pitch to the studio, then never talk to them until the test screening.

So there was one point I thought I was gonna lose it, but once I get on something I have to finish it; I just kept persuading them and they turned around. One good thing was the international guys really stood behind this movie, they thought they could support this film. So these guys step up and that's really good, and then they turned around.

These days I'm mostly familiar with two parts of L.A.: one is movie culture, and the other is Asian culture. The Westside is work, and the Eastside is Chinese - which means my friends.
