Begotten

Begotten is a 1990 American experimental dark fantasy horror film written, produced, edited and directed by E. Elias Merhige. It narrates the story of Genesis while reimagining it.

The story opens with a disfigured man bleeding uncontrollably and beginning to scar himself in flames. A robed, profusely bleeding God disemboweling itself, with the act ultimately ending in its death. A woman, Mother Earth, emerges from its remains, arouses the body, and impregnates herself with its semen. Becoming pregnant, she wanders off into a vast and barren landscape. The pregnancy manifests in a fully grown convulsing man whom she leaves to his own devices.The Son of Earth meets a group of faceless nomads who seize him with what is either a very long umbilical cord or a rope. The Son of Earth vomits organic pieces, and the nomads excitedly accept these as gifts. The nomads finally bring the man to a fire and burn him. Mother Earth encounters the resurrected man and comforts him. She seizes the man with a similar umbilical cord. The nomads appear and proceed to rape her. Son of Earth is left to mourn over the lifeless body. A group of characters appear, carry her off and dismember her, later returning for Son of Earth. After he, too, is dismembered, the group buries the remains, planting the parts into the crust of the earth. The burial site becomes lush with flowers. Grainy photographs of God Killing Himself are shown. In a final coda, Mother Earth and Son of Earth are seen again in a flashback, this time wandering peacefully through a forest. ........
