"I've been boxing on and off for 15 years. I would never call myself a boxer. I'm just a sissy actor, but I'm kind of obsessed with the ritual - the jumping rope and the shadowboxing... People aren't afraid to hit me. I've gotten two bruised ribs. I'll mix in with guys who know what they're doing, though. They won't try to kill me." Actor Sam Rockwell likes to keep fit by stepping into the ring with trained boxers.
