Orphan twin boys are imprisoned by a cruel tyrant and raised to fight as gladiators. After growing to massive-muscled manhood, the sword-wielding sibs battle a dragon and other menaces in a rebellion against their captor. Bodybuilder brothers David and Peter Paul are "The Barbarians," in a wild action/fantasy that also stars Richard Lynch, Virginia Bryant, and Michael Berryman as the Dirtmaster. Next, Lee Majors trades bionics for a broadsword as "The Norseman," an 11th-century Viking prince who sails with his warrior band from Greenland to North America to rescue his father, who's been captured by Indians. Mel Ferrer, Cornel Wilde, and Susie Coelho also star. 177 min. total. Widescreen; Soundtrack: English.
