Continuity mistake: After the German is shot next to the poster, a stool and a vase magically appear next to him.
Continuity mistake: When the man whose passport is due is about to be shot, check the left side of the screen. There's a man with a black hat with no-one by his left. A shot later a man with a white hat and black beard appears.
Continuity mistake: While waiting for Ilsa at the train station prior to leaving Paris he and Dooley are getting soaked by heavy rain. When they board the train a moment later they are both completely dry.
Revealing mistake: Claude Rains pretends to be smoking in quite a few scenes but it is obvious the character does not inhale. Rather, he barely puts the smoke in his mouth each time followed by blowing out large puffs of smoke.
Other mistake: When the young Bulgarian man is winning at roulette, thanks to Rick, the croupier spins the wheel and releases the ball. When the ball lands on 22, he shouts, "Vingt et deux, noir farez pas." This means, "Twenty-two. The black didn't make it." The problem is, 22 is a black number. The black did indeed make it.
Suggested correction: The croupier is saying "Noir pair et passe" - 22 being black (noir), even (pair) and high (passe).
This same croupier also mispronounces the French expression "les jeux sont fait", meaning that all "all bets are in "the last word, "fait" modifies the noun "jeux", which means "games." In French, the word "jeux" is plural, but its gender is MASCULINE, so it should be pronounce "fay "the croupier pronounces it as if it were plural, FEMININE, by saying "faites "pronounced "fete." Have watched this movie a thousand times, and just realised the mistake tonight. Have been to Casablanca, and to Ricks...have also taught French for many years...I should have caught this earlier...rookie mistake.
Les jeux sont faits, surely?
Nope...he" is NOT saying "vingt ET deux", even though it sounds like that. He is NOT saying the word "et", he is simply extending the pronunciation of "vingt "in effect saying "vingt-uh "very common in colloquial French...However, see my remark below about how he pronounces " les jeux sont fait", finally, the correct way to say 22 is "vingt deux" no "ET" is ever needed. Will listen more closely to see how the pronounces the result of the wheel's spin relative to "passe."
