Hammer is an early film vehicle for Fred Williamson. I would not regard this as his best(or worst) film work, but he shows lots of natural charisma and has a good screen presence. He has some ultra stylish pork chop side burns to boot. He is a boxer that gets mixed up with a crooked manager, which goes good for a while, but when Hammer won't take a dive ,the fight between Fred and the syndicate is on. The film looks real good and has some good action and a good supporting cast with blaxsploitation regulars D'Urville Martin and William Smith, who is very tough and a great villain. This film is not one of the all time best but should please most fans of the genre as a decent time passer.
