Audio problem: After the Red Sea parts, and almost all of the Hebrews are across the dry expanse, the pillar of fire holding Pharaoh back disappears, and the chariots head into the expanse themselves to pursue the Hebrews. A very young Hebrew boy at the rear of the masses says 'Look, Grandpa! Pharaoh and his men are coming!' and points at them with his free hand. Watch his mouth: the child is merely moving his lower jaw up and down. Apparently the child actor was too young to learn any lines so the producers improvised.
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.
Answer: She was a woman scorned. Yes, she loved Moses, but Moses turned his life away from the royal life of Egypt (and Nefertiri's love) to be with his people, the Hebrews, and serve the will of God. These were far more important reasons to Moses than living a lush life as a prince of a people he was not connected to by blood or lineage.
