The eponymous first blaxploitation film for former NFL athlete and genre mainstay (sensing a theme yet? Blaxploitation gave more former athletes work then Dancing With the Stars) Fred "Hammer" Williamson, about a dockworker who becomes a boxer beholden to the mob. The climactic fight scene comes to a gruesome end when the hero breaks out his top-secret "Pumps and a Bump" move. Too legit!
