Moses is brought up thinking he's an Egyptian. This isn't obvious from Exodus, but it does create a satisfying character arc for him, going from spoilt brat to a leader of humanity. The film invents a daredevil race through the city, with Moses and his brother Rameses sending slaves scuttling into doorways as they gallop around in their shiny gold chariots, guffawing with princely entitlement. At one point, they even knock the nose off the Great Sphinx of Giza, which appears to be under construction. In real life, the Sphinx was built at around the time of Sargon of Akkad. Its nose probably wasn't knocked off until around three millennia after Moses, possibly by British or French troops.
