I grew up on movies about King Arthur, Guinevere, Lancelot and the rest off the knights from the 1953 film “Knights of the Round Table,” “Prince Valiant,” “A Connecticut Yankee in King Arthur’s Court,” and “Camelot” to John Borman’s 1981 sword and sorcery fest, “Excalibur.”
The closest Hollywood ever got to an Arthurian classic, which is not very, was Richard Thorpe’s 1953 Knights of the Round Table , a rather stolid but watchable affair starring Robert Taylor, Ava Gardner, and Mel Ferrer.
So much for all those legends we learned from Thomas Malory's immortal Le Morte d'Arthur (1470) and the less immortal "Knights of the Round Table" (1953).
If you're looking for something closer to the Arthur legends, or if you just want to see some old-fashioned knights in shining armor rescuing fair damsels in distress, you might consider John Boorman's excellent "Excalibur" (1981), the best of the lot; or "Ivanhoe" (1952), "Knights of the Round Table" (1953), "Prince Valiant" (1954), "The Black Knight" (1954), "Sword of Lancelot" (1963), "Lancelot du Lac" (1974), "Sword of the Valiant" (1982), "First Knight" (1995), "Dragonheart" (1996), the musical "Camelot" (1967), or even the zany "Monty Python and the Holy Grail" (1975).
