Prince Valiant is a 1997 Irish-British independent sword and sorcery film directed by Anthony Hickox and starring Stephen Moyer, Katherine Heigl, Thomas Kretschmann, Edward Fox and Ron Perlman. It is based on the long-running Prince Valiant comic strip of Hal Foster, some panels of which were used in the movie. The story is based on the myth of King Arthur. A young, inexperienced squire Valiant, masquerading as Sir Gawain, is sent to accompany the Welsh princess Lady Ilene, a guest at Camelot, on her way back home. Little he knows that, meanwhile, the evil sorceress Morgan le Fay has convinced the Viking warlord Sligon, ruler of the kingdom of Thule, to steal the magical sword Excalibur during a joust tournament.
