BOSS (1975)

 Way better known under it's original title of BOSS NIGGER (the DVD I own of this not only cuts "the n-word" from the title but also from the opening theme song) this is the story of a couple of black bounty hunters(Fred "The Hammer Williamson and that bad D'Urville Martin) in the old west. The story tales a sorta similar journey as Williamson's BUCKTOWN(also from 1975) where our heroes become sheriff of a town and pretty much take over. Unlike that film though it's still the olden days so things don't go very smoothly for our dark-skinned lawmen. They also have to contend with hulking, muscular badass William Smith and his gang of unruly outlaws who are not very progressively-minded to say the least.
 Directd by Jack "CREATURE FROM THE BLACK LAGOON" Arnold and written by Williamson himself this is a pretty interesting mash-up of blaxploitation and western that works really better as a novelty than a particularly good film but if you get sick of either of those 2 genres it's worth a watch. Also it makes a great double-feature with THE LEGEND OF NIGGER CHARLEY from '72 which also featured Williamson and Martin in an old west setting.
