Bale and Hardy decided it would be pointless to waste stuntmen on their dirty work. So they did it themselves, that's why Nolan filmed the fight scenes last. Both needed medical attention.
Rented this on VHS back in 1993. My 10 year old cousin in Montreal had nightmares and wet the bed for 3 days in a row after watching this. I enjoyed it (the film, not the bed wetting)
Bolo Yeung (above) was Bruce Lee's sparring partner. He also trainer Brandon Lee, Yun Fat Chow and Jean Claude van Damme. Bruce and Bolo were working out the Finale of Games of Death when Bruce died. To get an idea what that would look like you have to watch it in Dragon: The Bruce Lee Story.
