Fred Williamson produced and directed The Last Fight, but he didn't take the starring role. That honor is reserved for singer Ruben Blades, playing a chronic gambler who turns to prizefighting to pay off his debts. He rises to the top of the pugilistic world, disregarding the warnings of his doctor and the admonitions of his girlfriend. He then meets his match in the form of real-life boxer Salvador Sanchez (who died in an auto accident not long after this film was completed). Controversial boxing promoter Don King also plays a cameo in this agreeable Rocky wannabe.
