Author's Saving Throw: It's subtle about it, but this film seems to serve as a defense for why God ordered the complete genocide of the Amalekites in the Old Testament, including the children. A single pregnant woman surviving one of the Israelites' wars against the Amalekites led to her son coming within inches of causing the complete genocide of the Jews across the entire Persian Empire.
Magnificent Bastard: Haman. In contrast to his Biblical portrayal where he begs for his life after in the scene where Esther reveals his plan in front of the king, here he doesn't lose his cool and instead calmly casts doubt on her Jewish heritage, accusing her of trying to usurp a good position, then breaking speeches her as she fears the king may not believe her.
What Could Have Been: The film's publicity made much of the fact that this was the first time that Peter O'Toole and Omar Sharif had been in a movie together since their legendary turn in Lawrence of Arabia— except that, as several reviewers complained, they shared exactly zero screen time together, playing characters separated by a 400-year Time Skip. How hard (and how awesome) could it have been to put them back together for real?
