I always used to wonder why American actors were getting fat, then I made a U.S. movie. I'm seeing all the food every day, and there's lots of waiting around because making an American movie is very slow.

I love working with older actors because number one, I can learn so much from them because they have so much experience. And it's fun to hear their stories from their era, some of the jokes.

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

I got nominated for my second film as best young director in the Aikido Film Festival in Japan.

There are two types of Chinese growing up in America. One is the kind that does really well in school, with thick, thick glasses. And the other is involved with the gangs.

My action follows my characters. If a character is a cop, you cannot be posing all the time, you cannot fly off the roof because it doesn't make any sense - it's not practical.

My mum lives in Boston; she's famous for teaching wushu and t'ai chi. So from when I was young, my mum and aunt were like: 'You're training; you're not playing baseball or football.' Training every day was normal. Later, when I was almost a teenager, Bruce Lee became my idol.
