WU TANG CLAN (1980)

 Terribly re-titled as part of the rap group The Wu Tang Clan's collection on VHS. This movie has no mention of Wu Tang at all and deals with prisoners of the Shaolin temple. The interesting part of this one is that the prisoners are supposedly tortured but since, as everyone who has seen at least a couple of kung fu flicks knows, the similarities between torture and training are almost indecipherable which raises the question of whether they are actually being punished or trained by their captor who just purely coincidentally happens to be a former Shaolin student himself. From there everything kinda plays out like you would guess though and it goes on a bit long at an hour and 46 minutes but I guess you could do worse in kung fu cinema. 

 IMDB claims this was the inspiration for the Wu Tang Clan group's name which I'm pretty sure is impossible since this was originally called THE HEROES or THE SHAOLIN HEROES in English up until it's VHS release years later. Also usually this film is given that credit.
