Redbelt

Director and screenwriter David Mamet brings us the action film Redbelt, to be released May, 2008. It stars the British actor Chiwetel Ejiofor as a Brazilian Jiu-Jitsu teacher who "is pressed to enter the ring for pride and profit." It sounds like the plot for about half the martial arts films since Enter the Dragon, but Mamet wrote the intense play Edmond, and Ejiofor was confident, manly, and brilliant in Four Brothers. This movie should be at least half-decent.
