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 Jo comes home from New York and sees Beth sick on the sofa, she gives Beth a music box. Beth opens the lid to the music box and in the next shot, the camera is pulled back and Beth opens the lid again.
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: As John Wayne leaves the landing craft he loads a stripper clip into his bolt action 1903 Springfield rifle. A minute later his rifle has changed into an M-1 Garand.
Continuity mistake: When the cat hits a table after being thrown into the perfume shop, a bottle of white hair dye pours onto her tail and you can see the top of the bottle stop next to her. But when we see the cat a couple of shots later, the bottle top has gone.
Continuity mistake: When Sinatra comes down to Esther Williams to serenade her by the pool, she has just been swimming. When she meets up with him by the tree she is dry as a bone. Even her swimsuit is dry.
Continuity mistake: The movie begins with Joe Backett witnessing one of the many victories by swim star Eve Barrett. In the very first wide shot of the pool, Esther Williams is fitting her cap getting ready to compete. Cuts to a closer view, and she has a towel on her shoulders that she has to take off before fastening her cap. (00:01:45)
