Casablanca (1942)

Continuity: When Bogie is reading the note from Bergman, it is dissolved by the heavy rain and he is dripping wet, so is Sam, who delivered the note. But then he is standing on the step of the train totally dry.

Continuity: In the final scenes at the airport, when Rick is talking to Major Strasser, the epaulettes on Strasser's shoulders alternately appear and disappear.

Continuity: 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.

At no point in the film does anyone say "Play it again, Sam".

Conrad Veidt, who played Maj. Strasser, was well known in the theatrical community in Germany for his hatred of the Nazis, and in fact was forced to hurriedly escape the country when he found out that the SS had sent a death squad after him because of his anti-Nazi activities.

In the 1980s, this film's script was sent to readers at a number of major studios and production companies under its original title, "Everybody Comes To Rick's". Some readers recognized the script but most did not. Many complained that the script was "not good enough" to make a decent movie. Others gave such complaints as "too much dialog" and "not enough sex".
