Deathstalker

Deathstalker is a 1983 American-Argentine sword and sorcery film directed by James Sbardellati and starring Rick Hill, Barbi Benton, Richard Brooker, Lana Clarkson and Bernard Erhard. In it, a cynical antihero known only as Deathstalker (Hill) finds himself the unwitting participant in a warriors' tournament, set up under false pretense to wipe out all potential challengers to the reign of Munkar (Erhard), the evil mage who usurps a king's throne and holds his princess daughter (Benton) captive.
