The B-movie style is cool, but the acting is weak. Mickey Spillane's Mike Hammer has a temper, but this actor plays him like a hot-headed street punk; it's all wrong. For the real deal, watch KISS ME DEADLY.
3 stars for a strong storyline and a great script from Mickey Spillane himself. Peggy Castle does quite well as the femme fatale too. But the movie is badly let down by the casting of Biff Elliot as Mike Hammer. This could have been a 5 star movie if Ralph Meeker was Hammer.
