Continuity mistake: When Rick goes to see Ferrari at the Blue Parrot the first time, there is a bottle on the table between them. Ferrari is shown taking the cap off the bottle, pouring a drink, and then returning the cap to the bottle. In the next cut, the bottle is gone, and in the cut after that the bottle is back, but without the cap, which should still be on it. (00:56:05)
Factual error: When Rick is talking about the German guns shelling near Paris, he describes them as 77's (non-existent) - likely meant the famous 88's used as anti-aircraft and tanks as well as for wheeled guns. [The line was originally "88s" but was changed at the request of the War Dept. so as to not tip the German's hands that we knew about the 88s.] (00:44:25)
Revealing mistake: Dooley Wilson (a singer, drummer, and leader of his own touring band) who played "Sam" in the film, couldn't play the piano. A pianist was playing offstage while he sang the songs. If you look at Dooley's hands whenever he is 'playing' the piano, you can see that he is not playing the proper notes. (00:25:30)
Continuity mistake: When Ilsa is in Laslo's bedroom, she is shown from behind looking out the window at the street below, then after an edit she is shown looking at the street from out side the window. The problem is that the first shot showed her looking through a roll-type window shade, and the second is a slat-type Venetian blind.
Continuity mistake: When Rick and Renault are sitting at a table outside Rick's Cafe, a bottle disappears from the table between one cut and the next and then reappears. In the shot without the bottle, there seems to be a champagne bottle at an angle in the background, something that is not visible in the other shots when the first bottle is on the table. (00:16:00)
Factual error: Major Strasser uniform trousers have a double stripe running down the side. Double stripes were reserved for General Officers therefor Strasser would not be entitled to wear them.
Factual error: Major Strasser refers to Rick as a "bumbling American." Capt. Renault then replies, "We mustn't underestimate American blundering. I was with them when they blundered into Berlin in 1918." During World War I, no Allied soldiers ever attacked or occupied Berlin. In fact, when the war ended Germans still occupied some French territory. This led in part to the rise of Hitler and World War II because of the belief that Germany did not really lose World War I but was sold out by various conspirators.
Continuity mistake: In scenes at Rick's Cafe, Captain Renault is wearing a white dress jacket with three medals. The right-hand medal, possibly the Légion d'Honneur, is first seen on a long ribbon. Less than a minute later, it is on a short ribbon; over the next nine minutes, it becomes long, short, long. It's not a medal, it's a yoyo. (00:16:30 - 00:26:40)
Revealing mistake: When we see the shadow of Rick opening the safe, there is also the shadow of a candle centered in the shadow of an archway. When we see Rick closing the safe, the shadow of the candle is now at the edge of the shadow of the archway; showing that the two shots were lit differently. (00:18:00)jle
Factual error: The extras in the film that were supposed to be Moroccans are perfectly dressed as Egyptians.
Continuity mistake: In the beginning of the movie a man comes outside the door to look for Rick and the spotlight passes by him. When he walks over to Rick it passes by him again. All the other times the spotlight passed it took about a minute to come back around again. (01:12:00 - 01:15:30)ShooterMcGavin34
Factual error: The opening credits name S.Z. Sakall as S.K Sakall, and the globe of the world which follows the credits has the USSR listed as the Union of Socialist Soviet Republics. The original name of the USSR in Russian was "Soyuz Sovetskikh Sotsialisticheskikh Respublik" which translates as Union of Soviet Socialist Republics.
Revealing mistake: Near the very beginning of the film, we see the Moroccan police car with five officers speeding through the busy street with siren blaring and people jumping out of the way. The siren continues to be heard, as the scene shifts a total of five times within eight seconds to show the panic and confusion in the streets. As the siren continues, the scene shifts back to a glimpse of the police car once again, which is going through the same section of street, with the same buildings and painted mural and the same actors on both sides of the street. Watch the man in the white suit and hat jump out of the way of the same car two times within nine seconds. (00:01:00)
