Factual error: In the beginning, when the Germans are setting up the tables to record the names, one German puts down a plastic stamp pad. Stamp pads of that era were metal.
Continuity mistake: When the train with the female prisoners arrives at the concentration camp Auschwitz 2 (Auschwitz Birkenau), you can see the brick stones of the wall of the tower of the "Gate to Hell" as it was referred to. In the next shot the locomotive is first seen driving through the gate tower followed by the wagons thereafter. It is not possible to see the brick stones before the locomotive drives actually through the gate.
Factual error: When the camera took a shot on a train coming to a station in Czechoslovakia, you can see electric cables above the train tracks. There was no such thing in Czechoslovakia as electrified trains in the 1940's. The electrification started in the 1950's.
Factual error: When Amon Goeth attempts to execute the Jewish factory worker for failing to produce enough hinges, Goeth cycles the actions of both inoperative weapons several times. At no time is an unfired round ejected from either handgun, which should have occurred, unless the unfired rounds were both jammed in the chamber (and the firing mechanisms had failed).
Other mistake: Schindler is having the glass door of his office lettered. The style and size of how it is done changes during the scene.
Continuity mistake: When the Germans invade the Ghetto, one Jew pretends to be working for the Germans by picking up the luggage. He drops one suitcase right next to his foot when he salutes to the Germans. After the next shot which shows the Germans laughing, the suitcase is much further away from his foot.
Factual error: In the opening scenes at the nightclub when Oscar is treating his new friends to dinner, they are singing "The Happy Wanderer" ("Der Fröhliche Wanderer"). This song was written by Friedrich-Wilhelm Moller shortly after WWII. The nightclub scene was supposed to have taken place in 1939.
Revealing mistake: In the scene where the women are laying in their bunks in the work camp and one lady is describing what she heard about the horrors of other concentration camps, at the end one woman puts up her hands to her face. You can see her fingernails are neatly manicured, something you'd think wouldn't be possible in a forced labor camp.
Visible crew/equipment: When Schindler and Goeth are having a conversation in Goeth's villa, and Goeth says that he knows that Schindler wants his own sub-camp, you can see the shadow of the camera on Schindler's right arm.
Revealing mistake: In the scene where the woman engineer is executed by Goeth's henchman, watch closely. First, her hair goes from being clear of her forehead, before she is thrown on the ground, to hanging in a fringe, so as to conceal the makeup appliance that replicates her being shot. Then, when she falls, a tube can be seen attached to her leg from an appliance on the ground.
Factual error: When the train containing the women leaves Krakow-Plaszow and is mistakenly rerouted to Auschwitz (roughly 25 miles west of Krakow), the train is shown passing a mountain range. There are no mountains between Krakow and Auschwitz/Oswiecim.
Continuity mistake: Amon Goeth pulls out a German Luger to shoot the rabbi. The Luger jams so Goeth pulls out another pistol and pulls the slide back indicating a semi-auto handgun. The second also fails. Goeth gets frustrated and throws the gun on the ground. When the other Nazi picks it up, it's magically a revolver.
Continuity mistake: In a courtyard of a concentration camp, a fully-clothed Jewish man wearing an armband steps into a long line in front of a table. The camera shows a quick shot of something else, then comes right back to that same man. Now he is missing his armband.
