Corrected entry: In the final joust when Sir William knocks Count Adhemar off his horse you see Adhemar land on his face wearing his helmet but then you see him laying on his back without his helmet on plus he also appears to be stunned from getting knocked off the horse.

Correction: The directors DVD commentary explains that the "lying on his back" scene is happening in Adhemar's mind. That's why we see him get knocked off the horse twice. Once when the dream sequence starts and once when it ends.
