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 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: 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.
Continuity mistake: When Bugs is at the theatre, you can see he a man sitting next to him when he finds his binoculars, but when Bugs sees Elmer in front of him, we cut back to Bugs and the man next to him has disappeared.
Continuity mistake: When Bugs dons his top hat and tails and tells the penguin, "I've always wanted a nice long formal vacation", he takes the penguin by his left hand. When the two are walking along in the next shot, Bugs is now holding the penguin in his right hand.
Continuity mistake: When we see the radio at the beginning of the short, there is a chair positioned next to it. But when Porky walks past the radio after trapping the mouse in his hole, the chair is now by the wall.
Continuity mistake: When Chip and Dale fall out of the tree after Donald had drilled in a hole in it to get some nuts, Dale lands on the ground and you can see there is nothing on the bottom of the tree. But when we see Dale just a few seconds later, he is now sitting next to the tree and grass has suddenly appeared.
