Hawk the Slayer is a 1980 sword and sorcery adventure film directed by Terry Marcel, and starring John Terry and Jack Palance. The story follows two warring brothers who fight to gain control of a magical sword. A brave warrior, the titular Hawk, assembles a small force of fighters to help him rid the land of a powerful and devious enemy.

Marcel had been working with Harry Robertson when they realized that they both were fans of the sword and sorcery genre. Marcel has stated that it was not intended to include magic at all, and was supposed to be a historical film. In the course of writing the script, he then introduced the magical mind stone, changing the overall nature.

The film had an initial negative reception but has since developed a cult following. Sequels were planned, but never produced.
