Night of the Assassin (1980)

The swords never stop flying in this action-packed old school hit. Master Wu (Ko Keung from "Fatal Flying Guillotines"), after refusing to help the king continue his war, fights off a regiment of guards attempting to take him by force. Unfortunately, he cannot save his brother, but he can get revenge. Master Wu embarks on his journey for revenge and is joined by David Chiang ("Slice Of Death", "Challenge Of The Shaolin Masters"). Ninjas, gap-toothed kings, and a sword-wielding army are just a few of the obstacles Master Wu must overcome on his revenge quest.
