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.
