Gladiator Double Feature: Vengeance of Ursus (1963) / Colossus and the Headhunters (1960)

Colossus and the Headhunters (1960, Color): Legendary hero Maciste rescues a raft full of survivors from a volcanic island as it explodes into lava and ash. Adrift and starving, they finally find land far to the west, but soon realize they have stumbled into the middle of a brutal war between the civilized city-dwelling Urias and a tribe of headhunting savages. The bloodthirsty natives are led by Kermes, a power-crazed Urian traitor who would sacrifice his own countrymen in his quest to be King. But he hasn't counted on the sudden appearance of Maciste, who is eager to fight for the oppressed.
