If you've seen TV wrestling, you know what a "caged" bout is. In Cage, it's for real; two testosterone-pumped behemoths are placed in a cage where they duke it out to the death. Lou Ferrigno plays Billy Thomas, the muscle-bound Vietnam vet who is finagled into cage-fighting by a group of mobsters. Scott Monroe (Reb Brown), the man whose life Billy saved in Nam, finds himself (through a series of ludicrous plot twists) facing his former savior in the dreaded cage. We suppose this was meant to be taken seriously, but audiences didn't get the hint; Cage has been greeted with raucous, derisive laughter ever since its 1990 release.
