HAMMER (1972)

 Fred "The Hammer" Williamson took his nickname from this tale of a tough dock-worker who gets mixed-up in the boxing game and the mafia. That seems a little strange to me since Williamson would go on to do better, more memorable and more successful stuff(BLACK CAESAR) but I guess this is where his standard bad mother-fucker/lovable nice-guy character got started.  It has all the stuff you expect from a 70's blaxploitation flick including pimps, evil honkies, outrageous clothing, drugs and violence.  The strangest bit is probably a scene in a nightclub where a whip-weilding dominatrix-stripper does her thing.  A great supporting cast including the great William Smith as his typical monsterous musclehead character, that bad D'Urville Martin, that guy who played Goeorge Jefferson's brother on ALL IN THE FAMILY(Bernie Hamilton), Leon Isaac from PENITENTIARY(who is super young and looks like a little kid here) all do a good job.  The only downside to this is that it doesn't really ever go over the top in the action sense like some of the later black-action films and sticks to a basic boxing scam/mob plot but it's still a good watch even if just for historical reasons.
