Continuity mistake: When the Dowager Empress is walking towards the door and says the cinnamon smell is from an oil, her reflection in the mirror exactly matches her movements, including when she turns, when it should show a mirror image. Note the blue sash is on the same side in both. A quick reflection of Anastasia's head just before when she says "I just want to know who I am" has the same problem. After they sit the reflections appears to be right. (01:09:40)jimba
Continuity mistake: Anastasia's hair length changes throughout the movie; from fairly short at the beginning, to much longer when she puts on the dress Demetri bought her, back to a shorter length at the end when she's seen with her grandmother.
