When one train of the male Jews were taken to Czechoslovakia, we can see some electric columns for electric rail tracks. That could be impossible because till the end of War there was no electric tracks in that area. Even all locomotives were steam-engine.
In the 1940s, almost all European women did not shave any of their armpits, legs, or pubic areas, especially work or death camp women who were not allowed even the basics. All but one of the women in the film are trimmed and groomed.
When the Nazis are separating healthy and sick prisoners, they play two shellac records. The second disc is labeled "Fogg Records", but Mieczyslaw Fogg founded his record company after the war; moreover Fogg recorded mostly (if not only) Polish performers at his studio, and that song doesn't resemble a Polish song.
"Der fröhliche Wanderer" or "Mein Vater war ein Wandersmann," known in English as "The Happy Wanderer" was written after WWII. This is the song being lead by Oskar Schindler in the cabaret at the beginning of the movie.
(German version only) When Oskar Schindler and Goeth argue about the disposition of Helen Hirsch, we hear Goeth pronouncing the name of Auschwitz incorrectly, he says "Aus-schwitz". This error can be noticed at times in German public as people indeed seem to confuse the name of Auschwitz (which is German for the Polish town name Oswiecim) with "Ausschwitz" (where "ausschwitzen" actually means "to exude").
Oskar Schindler tells a guard, that only a kid can polish a 45 mm shell from inside. However, German army did not use 45 mm caliber guns at all (not counting a small quantity of captured Soviet tanks, for which the Germans did not manufacture ammunition anyway).
After the little boy takes the saddle out of the car and after
Oskar Schindler says thank you - he passes on some cigarettes to an SS personnel at the camp and Schindler calls him "Rottenführer", but the rank/insignia of the SS man responds to a different rank called Sturmmann which is one rank lower than the Rottenführer rank.
When Oskar Schindler takes his meal he uses his fork with the right hand and his knife with the left. Not being left-handed this would be a very unusual thing for a German man to do. In fact, Germans and many Europeans do in fact cut their meat with their dominant hand, and do not rotate utensils. Rather the meat is eaten straight from the knife, so the way Schindler eats in that scene is technically culturally correct.
Amon Goeth claimed to be an SS Major at his war crimes trial, and he is so described during the film. Recent examination of Goeth's service record has established that the highest rank he held was that of Captain.
After Goeth attempts to shoot the rabbi only to have his pistol fail to fire he pulls a second semi-automatic pistol from his pocket to shoot the rabbi. After this pistol also fails to fire several times Goeth hits the rabbi and walks away dropping the pistol on the ground. The pistol that he drops is a revolver and not the semi-automatic he removed from his pocket.
The Doctor who poisons his patient in an act of mercy killing is first seen covered in blood scrambling to get the poison from a pharmacy. Moments later he is seen in a perfectly clean identical coat when he is distributing the poison. A bit later he is seen carrying a wounded woman who is subsequently shot by an SS man, the former bleeding out on the doctor.
When the kid is painting the letters "DIREKTOR" for the first time, a serif font is used. In a subsequent shot the word is shown in a san-serif, bolder, almost stencil-like font. The size of the word is also much larger than before.
In the ammunition factory, Schindler approaches the rabbi working at a grinding machine from behind and asks him a question. The rabbi does not hear it, due to machine noise, so Schindler calls him a little louder. The rabbi then switches the machine off and answers the original question, which he did not hear and Schindler did not repeat.
When the men use a little boy to get ice from the roof of the train while they're going to Oskar Schindler's factory, the barbed wire on the window is in a zig-zag pattern, but the exterior shot reveals a line pattern.
Towards the end of the film, when the Russian soldier liberates the Schindler Jews who are sleeping outside of the factory, as he rides towards them on a horse there are lot of gaps on the ground between the sleeping Jews. Then the camera angle changes to a position behind the soldier, and there are far more people lying on the ground with no gaps whatsoever between them.
The sequence of Oskar Schindler interviewing for a secretary position opens with a wide shot showing furniture in the room that is covered while the walls are being painted. Once it cuts to a close shot, the furniture is gone.
The opening sequence in the train station, one can clearly see that there is no metal cover where the guy is setting up the table, yet as they begin to take names, it seems that the action is happening in a different place.
The scene inside the cellar between Oskar Schindler and the maid, when she faces the camera head on, there is no light coming from the right, yet as the scene progresses and the shot tightens, somebody turns on a light which becomes visible as they cut to her left and her head tilts forward.
The hanging of Amon Goeth looks absolutely nothing like the actual film footage of the execution. Place, clothing, procedures, number of people involved and the graphic events that took place are all wrong.
Among the decorations worn by Amon Goeth on his SS uniform are the Iron Cross 2nd Class, the Sudentenland Medal, and the Silesian Eagle. Goeth was never awarded any of these decorations; in the case of the Silesian Eagle, Goeth would have been 11 years old when the badge was presented.
In the scene where they are separating the healthy from the sick, one of the men running naked is clearly not circumcised. However, many of the Jewish prisoners were not Torah observant but in fact had been assimilated into Gentile society, and thus may not have been, in fact, circumcised.
Just after the little boy is held up to pull down another icicle from the roof of the train, the camera angle switches to the exterior and pulls back to show the train going by with no trace of snow or ice anywhere else on the train except right over that one doorway.
When Schindler is getting dressed to go to the night club at the beginning of the film he pours a clear liquid into his glass on the table next to the radio and lamp from a Hennessy VSOP Cognac bottle. Hennessy VSOP Cognac has a dark, amber color and wouldn't be clear for any reason.
When Goeth attempts to shoot the Rabbi for producing too few hinges, his semi-automatic pistol fails to fire. In order to re-cock the pistol, he racks the slide (pulls back the slide) several times. When the gun still fails to fire, he tries the same thing with a second semi-automatic pistol. Each time the slide is pulled back, we should see an unfired round being ejected from the gun, but this does not happen.
