Sword of the Valiant: The Legend of Sir Gawain and the Green Knight is a 1984 film starring Miles O'Keeffe, Cyrielle Claire, Leigh Lawson, and Sean Connery. The film is based on the poem Sir Gawain and the Green Knight, written in the late 14th century, but the narrative differs substantially.

Gawain was a squire in King Arthur's court when the Green Knight burst in and offered to play a game with a brave knight. No knights stand to defend their king's honor. Except for the valiant Gawain. After being quickly knighted Gawain plays the game, but learns that it's all a trick, and he has lost. But the Green Knight shows mercy, letting Gawain grow a year older before having to face the consequences. Gawain journeys across the land, learning about life, saving damsels, and solving the Green Knight's riddle. Written by Sean Kilby and Jason Parker
