Kung Pow! Enter the Fist

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.

The Chosen One begins training showing cartoonlike feats of strength, while Wimp Lo deems him an enemy out of jealousy. Soon The Chosen One learns that Master Pain, the man who tried to kill him as a newborn, has just arrived in town, so The Chosen One goes to find him.
