Continuity mistake: Near the end, when Sir Mador is hit with the small crossbow bolt, the impalement changes. In the first shot it's protruding from his abdomen well above his belt, but in the next shot the crossbow bolt is now lower, actually pierced through Sir Mador's leather belt. (02:00:30)
Continuity mistake: When Guinevere is about to meet Arthur for the first time, her hair is down when she's in the carriage and when she steps down to the ground. However, in the next shot of her walking forward, her hair is pulled back and twisted intricately with a ribbon. (00:29:46)
