Other mistake: King Arthur is on the far right of the scene as Guinevere is led away by the guards and he nods at someone off camera, asking them if it's OK to start acting as the camera moves around.
Camelot (1967)
1 other mistake
Directed by: Joshua Logan
Starring: Richard Harris, Vanessa Redgrave, David Hemmings, Franco Nero
Continuity mistake: The garden on the left side of the road to the Camelot castle changes in height, dramatically, from scene to scene. When Lancelot first encounters Arthur the garden is freshly harvested and cut. Later, the garden is lush and green.
King Arthur: Proposition. It is far better to be alive than dead.
