Excalibur (1981)

Jules: Not only an impossible love-triangle, but an impossible political romance unfolds in this robust and sinewy retelling of the ancient, troubadour-filtered tale of a God-given head of state who both physically and metaphysically unifies his island kingdom. The myth of the benevolent dictator finds its apotheosis in the overwhelmingly decent, occasionally-befuddled character of Arthur, whose innocence both makes and unmakes his dynasty.

David: The legendary expounding of how, when your best friend steals your girlfriend, literally everything turns to excrement. Meanwhile, metaphysical mentor Merlin meddles with ruthless benevolence in the affairs of men, watching with a pained fatherly expression as time after time they hold the prize of a golden age in their hands, and drop it.
