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 does he know that meanwhile, Arthur's wicked sister Morgan has retrieved a spellbook from Merlin's tomb and convinced the Viking warlord Sligon, ruler of the kingdom of Thule, to steal the magical swordExcalibur during a joust tournament. Valiant and the princess become part of the struggle of "he who holds the sword rules the world" which leads them both to love and Valiant to his princely destiny, as it turns out he is the rightful heir to the throne of Thule. The usurper is killed by his also evil brother Thagnar. During the final confrontation, with the help of Thule's ruler Boltar, Morgan is destroyed, Thagnar is slain, and Valiant rescues the princess and recovers Excalibur.
The film was recut by German producer Bernd Eichinger without the knowledge of director Anthony Hickox. In his autobiography Size Matters Not: The Extraordinary Life & Career of Warwick Davis, Warwick Davis, an actor in the film, called it an "absolute disaster" which was "premiered, panned and bombed," and "even the wonderful Joanna Lumley - who still managed to put in an amazing performance as Morgan le Fay - couldn't save it." He blames this on the director, who he says "seemed intent on partying all night long and giving roles to his friends." His best friend, Captain Crunch, can be seen in various shots within the movie.
Reception
The film was generally poorly received. Empire gave Prince Valianttwo stars out of five and stated, "a promising, swashbuckly romp is entirely scuppered by some indiscriminate broadsword editing, thereby removing any fun the name cast might have had, and leaving a poorly dubbed, effects-lacking film disappointingly limp." Some other reviews, however, were more positive. According to Sunday Mail, movie critics have been arguing for years over Prince Valiant, which was even called "one of the worst films ever." On the other hand, The Telegraph included it among top ten Arthurian films in 2014.
