Hercules the Avenger (1965)

Reg Park returns to his antics of old as the man of iron in HERCULES THE AVENGER. The Son of Jove undertakes another journey into the nether realms battling zombies and monsters in order to rescue his son, allowing goddess Gia an opportunity to place her own slacker son in Hercules' sandals. There's something for everyone: ghouls, dragons, sweating men and girls in skimpy outfits.
