Duel of the 7 Tigers (1979)

Great and really entertaining Kung-Fu movie

Plot:
Defeated in a match at Shaolin, Wu Kung wanders China till he finds his own temple and style of fighting: Tang Sao Do Karate. Years later, student and ninth successor, Hsi Man Kwong challenges and crumbles all the Chinese kung fu schools in the area.

This movie is so cool because you have seven kung fu masters, each with a unique fighting style, duking it out with a Japanese karate master. The coolest part is that each style–Hun Gar, Wing Chun, Monkey Fist, Choy Lee Fut, and others–gets its own part of the spotlight and a neat description to accompany it. The opening credits provide an impressive display of masters and these styles
