Excalibur

A motif from Wagner's Götterdämmerung, which was used prominently in Excalibur as the theme for the sword Excalibur is a 1981 epic dark medieval fantasy film directed, co-written and produced by John Boorman, that retells the legend of King Arthur and the knights of the Round Table, based loosely on the 15th-century Arthurian romance Le Morte d'Arthur by Thomas Malory. It stars Nigel Terry as Arthur, Helen Mirren as Morgana, Nicholas Clay as Lancelot, Cherie Lunghi as Guenevere, Paul Geoffrey as Perceval and Nicol Williamson as Merlin. The film is named after the legendary sword of King Arthur that features prominently in Arthurian literature. The film's soundtrack features the music of Richard Wagner and Carl Orff, along with an original score by Trevor Jones.

Boorman's Excalibur began development as an unproduced adaptation of The Lord of the Rings. The film was shot entirely on location in Ireland and at Ardmore Studios, employing Irish actors and crew. It has been acknowledged for its importance to the Irish filmmaking industry and for helping launch the film and acting careers of a number of Irish and British actors, including Liam Neeson, Patrick Stewart, Gabriel Byrne and Ciarán Hinds.
