When I'm in meetings until 5am and then have to get up two hours later for filming, sometimes I ask myself 'why?'

I know that eventually, I'll have to change my life and my career, but I've got a lot of good years left in me yet.

Do you understand the words that are coming out of my mouth?

If you're too free, you're like the way Hong Kong is now. It's very chaotic.

American stuntmen are smart - they think about safety. When they do a jump in a car, they calculate everything: the speed, the distance... But in Hong Kong, we don't know how to count. Everything we do is a guess. If you've got the guts, you do it. All of my stuntmen have gotten hurt.

Very difficult to understand American audience, what they like, what they don't like. Some movie I like very much, it doesn't work. Some movie I don't like, it gets big box office. Very difficult.

Martial arts is not for hurting people, it's for protecting people.
