Continuity mistake: When Moses and Joshua are reunited and Moses denies God's purpose for him (he says "I am not the man"), Moses has his arm around Joshua's back. In the next shot, Moses is only touching Joshua on the shoulder.
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.
Visible crew/equipment: At the start of the Exodus, the Narrator states, "After the stifling night of terror, came a day such as the world had," and just as the Narrator continues to say, "never seen," a crew member wearing a white short-sleeved shirt and dark pants is visible walking in the background, at the right side of the screen.
Visible crew/equipment: When Rameses is on his chariot ready to pursue the slaves, he shouts, "Forward!" In the next shot, there are visible wide tire tread marks on the ground from the camera vehicle, alongside the chariot wood wheel marks. (03:15:40)
Continuity mistake: When Moses returns from Ethiopia amidst great fanfare, he's wearing two golden wings crisscrossed across his chest. At first they are crisscrossed with his left wing over his right, but when Moses kneels in front of Sethi, the wings are crisscrossed the opposite way, with his right wing over the left. These golden wings continue to switch positions repeatedly in the following shots. (00:21:20)
Other mistake: In the Bible, Moses had two sons, not one (Gershom) as depicted in the film. He had both sons in Midian before he came back to Egypt to redeem the Jews.
Revealing mistake: When the parted Red Sea comes together, if you look behind Pharaoh as his troops are being engulfed by the water, notice in the background that there are two boulders floating in the water, not being pushed, but floating lightly.
Other mistake: When Rameses places the dead body of his son on the statue next to his throne, watch as it cuts to a shot of the side of the statue. A dummy was used in this scene, and it becomes obvious. Check out his hair, which looks like plastic, and his eyes, which look like little circles.
Other mistake: When Moses notices the burning bush, he tells Joshua that it is a bush on fire, but not burning. It's too far away for him to see that it's not burning.
Other mistake: At the very start of the Exodus there are three consecutive shots with the blowing of horns. In the next shot, while the camera faces the ground, there are multiple imprints of modern work boot or sneaker soles visible on the dirt (near the spotted goat), on the left side of the screen. These are not sole imprints of the time period. (02:59:25)
Revealing mistake: When Moses takes the first journey up Mt. Sinai for his very first view of the burning bush, the walking scene shot has Charlton Heston following the camera as the camera dollys backwards towards the bush. As Heston and the camera movement comes to a halt, two long tire tracks in the sand created by the dolly truck that housed the camera and cameraman can be seen.
Revealing mistake: All of the women in the film have 1950's-style haircuts.
Factual error: When Rameses is casting Moses out into the desert, he stands in his chariot. The pyramids behind him is the Saquara pyramid, so Moses is being sent West into the Sahara, and not East into the Sinai.
Factual error: When Moses is received by the Pharaoh after his Ethiopian campaign, he greets the Pharaoh with a Roman salute (right fist on left shoulder).
Revealing mistake: When Rameses is casting Moses out into the desert, he stands in his chariot and delivers his speech about ruling over the scorpions. The pyramids behind him are 20th century photos, i.e. they look 4000 years old. In the time of Rameses, they would have been substantially newer - 1000-1500 years old.
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)
Revealing mistake: When Rameses is casting Moses out into the desert the place where the real set ends and a painted panel starts is noticeable: The yellow sand becomes dark brown and the sea behind remains still all the time.
Visible crew/equipment: When Moses is brought in chains to Pharaoh's throne dais, standing behind Sethi and Nefritiri are two fan-bearers, one at the left and one at the right. In the two medium close shots of Sethi and Nefritiri, when Sethi tells Moses, "Speak, my son," the two actors' curved white marks are visible on the floor, at the right feet of both fan-bearers. (01:30:50)
Visible crew/equipment: When the High Priest tells Pharaoh about the astrologers seeing a star enter into the House of Egypt, the actor's white tape mark is visible on the floor, at his feet. (00:09:50)
Audio problem: When Moses' wife Sephora is out guarding the sheep, Moses is with his son at a tent. Sephora calls him because there is a stranger behind the rocks. When she calls you can hear that the sound is indoor-sound from a set, not outdoors. This continues when Moses calls, the dogs bark and so on.
