When Maria types the memo to put under the pillow, she types two lines with a total of 18 keystrokes. However, the actual memo is four lines of about 80 plus keystrokes (not counting spaces).

Early in the movie when Maria Tura is arguing with the play director about her dress, they begin onstage in the Gestapo office set. At one point, the director switches to a closer shot, and they suddenly are backstage, facing in entirely different directions than they were onstage.

When the actor portraying Hitler goes out on the street; there is a crowd surrounding him. However in the following shot when the kid asks him for an autograph, the orientation of the crowd has changed.

When the young soldier is in the dressing room; he is on camera left and Maria is on camera right near the couch. However on the cut when he gets ready to leave the dressing room; he is now on camera right while Maria is on camera left near the dressing mirror. It was not a reverse angle shot therefore the orientation of the actors changed from one shot to the other.

When the actors are on stage listening to the radio regarding Hitler; the orientation of the actors changes from one shot to another.

When Tura is disguised as Colonel Ehrhardt in his meeting with Siletsky, he is wearing the uniform of a Major General (actually an SS-Gruppenfuehrer).

The troupe of actors are all Poles but they somehow are able to deceive the Germans playing Germans without being able to speak German (or at the very least without a Polish accent).

When you see a shot of the hotel that the Germans had taken over and made their headquarters; the name is displayed as Hotel Europejski. That was the original name however, during the occupation, the Germans renamed it, Europäisches Hotel.

When Professor Siletsky (Stanley Ridges) first sees Maria out of his apartment, the door doesn't close properly and comes slightly ajar; this causes a momentary hesitation from Ridges before he walks away.

The same footage of the long shot of the audience with Joseph Tura's back turned to the camera is used for both of his performances of Hamlet.

During the flight to Warsaw, the wire holding the obviously model airplane is visible.

Although having Maria Tura give the cue line "To be or not to be" to the men in the audience she wishes to meet in her dressing room is a very funny premise of the film, it actually would be highly impractical for Maria to think she would have time to meet backstage. Hamlet's "To be or not to be" soliloquy is only about 3-4 minutes long and Ophelia has the very next line in the play (in fact Hamlet announces her entrance at the end of his soliloquy), which would barely give Maria any time to meet men in her dressing room.

When Maria returns to her apartment after being at Siletsky's office; she states that she was at the Hotel Europa. However, the name displayed on the hotel's awning is Hotel Europejski.
