I can't find the exact quote, but the story goes that someone once asked Bruce Lee why most martial arts films were period pieces, and he replied by pantomiming shooting a gun and saying, "That's why."
Japanhero26- That reminds me of the famous sword vs. gun scene in Raiders of the Lost Ark. The back story for that is pretty funny. To quote from the Wikipedia article, "The fight scenes in the town were filmed in Kairouan, while Ford was suffering from dysentery. Stuntman Terry Richards had practiced for weeks with his sword to create the scripted fight scene, choreographing a fight between the swordsman and Jones' whip. However, after filming the initial shots of the scene, after lunch due to Ford's dysentery, Ford and Spielberg agreed to cut the scene down to a gunshot, with Ford saying to Spielberg 'Let's just shoot the sucker'. It was later voted in at No.5 on Playboy magazine's list of best all time scenes."
