Footage was used from the film Bruce Lee la tigre indomabile (1976) (original Mandarin title "Hu hao shuang xing", or "Tiger & Crane Fists"). Actors were digitally inserted into scenes from the original film. Steve Oedekerk specifically chose to parody the film out of dozens of other kung-fu movies due to the scene of the villain being hit in the crotch numerous times without flinching.
