Hercules (Reg Park) rescues a princess (Laura Efrikian) left to be prey for a monster but then must protect her further from her wicked mother, the queen of Atlantis (Fay Spain). Not the most thrilling of adventures for the Greek hero, but reasonably entertaining nonetheless. Original title: Ercole alla conquista di Atlantide.
Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
Movie 413 for 2021.
