Hercules Against the Sons of the Sun (Italian: Ercole contro i figli del sole, Spanish: Hércules contra los hijos del Sol, also known as Hercules Vs. the Sons of the Sun) is a 1964 Italian-Spanish peplum film written and directed by Osvaldo Civirani.

[2][3] Hercules (Forest) is shipwrecked in the land of the Incas after a month-long storm that drove his ship across the Great Ocean, which he believes occurred because the crew somehow angered the god Neptune.

The only survivor, Hercules is attacked upon awakening on the beach by Inca warriors, but these are slain by Inca rebel archers under the command of Prince Maytha (Gemma), son of the rightful Inca King who has been usurped and imprisoned by his own brother, Ata Hualpa (Fantasia), as has Maytha's sister, Princess Yamira (Pace).

Though Maytha earlier promised to help Hercules build a ship to return to his home, at the end the Greek hero embraces Princess Yamira.

and "an array of spectacular costumes" concluding that "its decorative virtues are the film's only strong point: it is totally lacking in vitality, and the stiff acting is not improved by equally stiff dubbing".
