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: 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: 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: After the ill-received Al Jolson impersonation, Milton Berle gets paid only 5 bucks instead of 50. He asks the manager "What are you doing, putting 45 in your own pocket?" as several not so reassuring individuals begin to crowd him. Notice a balding guy with a white shirt and pattern tie; he puffs out smoke as he arrives, but at the cut he is still chewing on his cigar and immediately blows smoke again.
Continuity mistake: At the beginning, Gregory Peck is in bed, tied down, when a storm opens his windows and blows out the candles. But when Ava Gardner walks in and closes the windows, the candles are alight again.
