Revealing mistake: When Natalie Portman's character is about to be executed, if you look at the wall behind the executioner, you can see a modern metal drainpipe.
Audio problem: In the scene where Mary is leaving court and you see Henry riding a horse with Anne on the back, you can hear a siren go off twice. (01:05:30 - 01:06:10)
Continuity mistake: The morning after her wedding night, we see Mary walking with Anne telling her about the wedding night, notice Mary's braids in her hair, one braid is in a circle, yet in the next scene where Mary and Anne are folding a blanket, her braid is now down in one long braid. (00:12:20 - 00:15:30)
Continuity mistake: When George comes in to get Anne before going into Mary who is getting ready for her wedding, Anne's headress changes, at first she is seen wearing a more decorative one and as her and George come around the corner and head to Mary's room her headress is completely different. (00:12:15 - 01:12:15)
Audio problem: When Lady Elizabeth complains about the king coming to visit, Sir Thomas says, "That's easy for you to say you've had position and wealth all your life," and she replies, "Until I married you Thomas." When the camera faces Sir Thomas we hear Lady Elizabeth say, "And I was happy to give it up for love," but her lips do not move while saying this.
Chosen answer: It is unknown who the older girl is, but probably the child of a close relative. In the movie (which significantly differs from the novel and from history), Mary is shown to only have given birth to one child (King Henry's son) before her marriage to William Stafford. Therefore, the girl could not be Mary's child by her first marriage.
