Emotions serve characters' purposes. That is their motivation.

I don't have a checklist. Whatever material excites me, they'll call for a certain genre or combination of genres. It'll come naturally and I'll be eager to learn how that thing works. I learn the rules, and I'll probably break some of them.

I think the book struck me in a few ways that I thought very interesting to pick it as my first martial arts film. It has a very strong female character and it was very abundant in classic Chinese textures.

I grew up pretty much prevented from knowing anything from Communist China except that they were the bad guys that stole our country.

Sometimes films ignore other points of view because it's simpler to tell the story that way, but the more genuine and sympathetic you are to different points of view and situations, the more real the story is.

I had to find my way of translating the excitement you get when you're reading comic books to the big screen.

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.
