Legion of Iron (1990)

It's an ordinary date night for Billy (Kevin T. Walsh) and Alison (Camille Carrigan) until mysterious forces whisk them away to an underground arena, where Billy must fight other captives for the wagers of wealthy men and the pleasure of Queen Diana (Erika Nann). When he's not battling for his life or protecting Alison from Diana's lecherous bodyguards, Billy attempts to rally his fellow slaves into a full-blooded revolt.
