Hercules in the Haunted World (Italian: "Ercole al centro della terra", lit. "Hercules at the center of the Earth") is a 1961 Italian sword-and-sandal film directed by Mario Bava. British bodybuilder Reg Park plays Hercules while British actor Christopher Lee appears as Hercules' nemesis Lico. Shooting at Cinecittà, director Mario Bava used some of the same sets from the earlier "Hercules and the Conquest of Atlantis" which had already starred Reg Park.
