The 12 labors of Hercules were not the objective of this film starring Lou Ferrigno as the semi-divine son of Zeus and the mortal Alcmene. Hercules must rescue Princess Cassiopea from her kidnappers, fight off grotesque laser-breathing monsters and in one case, jettison a giant bear up into space where it becomes Ursa Major, the Big Dipper or "Great Bear" constellation. Off-color (many scenes are in dim, bluish stage sets) and low-budget, this incarnation of Hercules may find unconverted viewers a difficult, 13th challenge to conquer.
