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.
Revealing mistake: In the big temple finale, you can see that huge blocks of stone are bouncing around as they hit the floor.
Teresh: Out of the strong came forth sweetness? Hah! The fruit of the date palm! The tree is strong, and the fruit is sweet.
Semadar: Teresh, what on earth you feed date palms to make them eaters?
