Continuity mistake: When Eleanor talks to herself in the mirror before Geoffrey enters, the Katherine-Hepburn wave in her hair is different when her reflection is shown. (00:59:45)
Continuity mistake: When Eleanor comes to free Henry's sons from the dungeon, the officer who is accompanying her stabs the guard in the throat. When he pulls the dagger out there's blood only on one side and nothing on the straw when the guard is kicked across the floor. (01:53:20)
Continuity mistake: In the last scene of the movie Eleanor leaves by boat to go back to her castle prison. When we see Henry waving good-bye he is standing right next to a post when we see him from the back, but this post is nowhere when he is shown from the water. (02:08:10)
