The Beastmaster [1982, USA, fantasy, adventure, DVD5]

Maax is a twisted cult leader out to steal the throne of King Zed. King Zed then banishes Maax, but Maax sends one of his three witches to steal Zed's unborn son. Ripping him right out of his mother's womb with magic and placing it a cow's womb, she takes him to die. Then a brave hunter kills the witch, rescues the baby boy, and takes him home to raise as his own. He names him Dar and while the boy is still very young, his new father finds out that he possesses the power to communicate with animals. Later, Maax sends his horde of thugs to wipe out the peaceful village that Dar calls home. However, thanks to a brave dog, Dar survives again and plans to use his powers to kill Maax to avenge his people and his foster father.
