Kung Pow! Enter the Fist is a 2002 American martial arts comedy film that parodies Hong Kong action cinema. Starring Steve Oedekerk, it uses footage from the 1976 Hong Kong martial arts movie Tiger and Crane Fist (also called Savage Killers), along with new footage shot by Oedekerk, to create an original, unrelated plot.
