Continuity mistake: The young son of the Chinese owner of the violin is near-sighted and his glasses have concave lenses. When he attends the auction as an adult he is far-sighted with incredibly thick convex lenses.
Continuity mistake: In the beginning of the film, when the wife of the violin builder dies, he sits with her dead body while she is covered in bed. Her arms are uncovered in one scene, and under the covers in the next.
Trivia: When the servant is reading the Italian woman's cards, look at the justice card. It pictures a person in front of a red flag with a yellow star, a lot like the Chinese flag. In the next scene, (after the children's performance), the Chinese woman is standing at her podium in front of a Chinese flag; red with yellow stars.
