This is from the sublime, somewhat controversial movie Excalibur (1981), which examined the legendary early mythos of King Arthur, the late Celtic-Romanic king of legend, who might possibly have existed in the 600’s-700’s AD.

Centuries later, Thomas Malory gave these stories some real wings, and I always loved those stories as a lad. Now, I’ve seen various productions over time when it comes to the Arthurian mythos, but I’ve always felt that the Boorman film (1981) was levels above, really.

Here’s a two-part scene from that… beknighted movie:
(in which Arthur has previously pulled the late Uther’s sword from the stone)
