Black Samurai (1976)
A 1976 film starring Jim Kelly... that does not have any Samurais in it. It is however chaos incarcerate with everything that appears in the film.
Here's the Riff package: kung-fu, a mariachi band, a vulture, a jet-pack, a sassy black woman, cool sound effects, a car-chase, and random explosions. Also, there's Santanic Worship, a secret agent organization, a fire-spouting pen, snakes, afros, a scene where the good guy kills tons of badguys with a grenade because why not dammit.
Checks off a majority of the features a Blaxploitation film would have. Makes one wonder if Pam Grier, the original action girl, was approached for a part in the film and she turned it down. Imagine... a film with William and Coffy fighting crime together... with all of the above listed.
