Quotes: David Mamet: "What I’m trying to do throughout the movie is show, fight by fight, the different ways in which today in Hollywood these actual guys use jiu-jitsu. The cops use it, the bouncers use it, the special forces use it. So there are different fights about how it would be applied in each of these situations."
