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. I say, "Do it! Camera, action, jump!" Boom! Ambulance! Hospital! Next stuntman!
