Continuity mistake: In the final destruction-of-the-temple scene, the huge statue of Dagon starts to topple head first, but in later shots it is sliding towards the camera feet first. This is because director Cecil DeMille was not satisfied with the first take and had the temple re-erected then collapsed a second time. Shots from both destructions are spliced together in an exciting sequence, but rather puzzling architectually.
Continuity mistake: In an early scene at Broderick Crawford's dinner table, his wife comes in to pour a cup of coffee. Half the coffee she pours ends up in the cup, the other half she spills on her hand and the table, yet no one seems to notice.
Continuity mistake: In the scene where Mary is eating her oatmeal while Martha is talking to her, take a look at Martha. While talking to Mary she spits out a piece of bread she was eating and this causes the little girl who plays Mary to momentarily slip out of character and smile (almost ready to laugh).

Continuity mistake: During Adam's summation, the close up shots of Amanda show different reactions to his speech. The long shots show her just sitting there, not reacting. This goes back and forth several times.
Continuity mistake: When the butler tells of Harry Lime's death, at the start of the conversation he can hardly speak English. As the conversation goes on, his English gets better and better, until at the end it's perfect with just an accent.
Suggested correction: He is reluctant to speak English at the start possibly to avoid trouble but later decides otherwise.

Continuity mistake: When Bugs emerges from his hole at the start of the cartoon, you can see there is some dirt around the hole, but when we see a close-up of Bugs in the next shot the dirt has gone.
Continuity mistake: When we first see Bugs at the Opry House, you can see behind him there is a pink poster with "Frizby the Magician" on it, and on the left there is a yellow poster. But when we see Bugs in the next shot, the "Frizby" poster is now yellow, the poster on the left is now red and a "World's Strongest Man" poster has appeared on the right.
Continuity mistake: When Tweety is running away from Sylvester, he hides in a tube of "Badminton Birds." When Sylvester comes around the corner, you can see there is a racquet next to the tube, but when we see Tweety coming out of the tube in the next shot, the racquet has disappeared.
