This double bill stars bodybuilder Reg Park in two of Italy's more lavish Hercules films. First, Hercules and Androcles journey to Atlantis to confront an evil queen bent on world domination. The mythic duo returns in Prisoner of Evil, where a sorceress seduces Herc and transforms him into a mindless beast. Italian horror master Antonio Margheriti directed this installment of the Hercules legend, a blend of sword-and-sandal fantasy and horror.
