Continuity: In the scene where Walter is telling Kitty he wants to divorce her, Kitty's necklace (with Charlie Townsend's ring) disappears and reappears between shots.
Continuity: In the scene where Walter is telling Kitty he wants to divorce her, Kitty's hair changes between shots, moving from over her left cheek to further back and then forward again repeatedly.
Continuity: In the scene in the orphanage where Walter kisses Kitty goodbye before he leaves for the camp, Kitty is sleeping with a child in her arms. The child is lying on his side as Walter kisses her, then a wider angle is shown and the child is all of a sudden sleeping on his back.
Continuity: During the love scene between Kitty And Walter, Kitty takes Walter's shirt off while they are kissing. In the next shot, Walter has his shirt back on and in the shot after that, when they are falling onto the bed, he has the shirt off again.
Plot holes: In the time and part of the world that the film is set in, racial and ethnic bigotry was overt, with an even greater emphasis placed on one's "purity". Those who were ethnically or racially "impure" were doomed to a life of utter misery and poverty at the very bottom of the social order. In short, there is no way that the film's Yu would have been mustered into the army, much less, become an officer.
Factual errors: As the film begins Walter Fane states that he is a bacteriologist. Arriving at the cholera village he explains to the locals that he is an M.D. specializing in control of infectious disease. Those are not the same occupation.
