I saw this the other day, and it must be the funniest film ever.
They took some Seventies martial arts film and used computer gimcrackery to put the director in place of the main character. Then they completely rewrote the dialogue and put in a couple of extra scenes. It's comic genius.
Sample scene - venerable kung fu master challenges evil bad guy to fight. Evil bad guy gets minion to put on MC Hammer for him to fight to.
