The Adventures of Hercules (also known as The Adventures of Hercules II) is the 1985 sequel to the film Hercules. It was written and directed by Luigi Cozzi (who also directed the previous film), and had Lou Ferrigno reprising his role as the title character.
The film begins in outer space, just as the first film does, and begins with a retelling of the Universe's creation story (see below). This is followed by the opening titles which are accompanied by short clips that highlight the key parts of the first movie.
The plot begins with a story about the story of Zeus' Seven Mighty Thunderbolts that kept peace. One day, other vengeful gods (Aphrodite, Hera, Poseidon, Flora) stole these lightning bolts to create chaos. The lack of these thunderbolts has rendered Zeus powerless and sent the Moon on a collision course with the Earth. As the humans on Earth begin to suffer, one human named Urania speaks to the Little People and learns that only Hercules can save them now.
