Continuity mistake: When Moses leads the Hebrews from Egypt, he pauses before them to deliver a little speech before they head out into the desert. He faces the camera and lifts his staff up with his left hand. But on the cutaway shot from behind, he is holding the staff in his right hand.
Continuity mistake: When Moses confronts his Egyptian mother Bithiah with the Hebrew piece of cloth, she is beading on an Egyptian loom. During this scene, the string that she is beading (the farthest to our right) first matches the height of the other strings. One shot later, there is suddenly more beads, making the string higher than the others. (00:57:40)
Continuity mistake: The distance between Rameses and Moses alternates from elbow to elbow to about three feet apart as the shots change when the duo are facing Seti during the Ethiopian tribute scene.
Continuity mistake: When Nefertiri and Moses are saying their goodbyes in the cave, his shackled right hand starts to stroke the upper left side of Nefertiri's hair, but the next cut shows Moses' hand lower down.
Continuity mistake: After Rameses slaps the coin out of Dathan's hand, the shot cuts to Dathan being much closer to Rameses. Another instant cut and Dathan is further from Rameses again.
