7. Not making lightsaber noises under your breath is *actually impossible*
Even the consummate professional Ewan McGregor couldn't stop himself from hmmzzzing as he swung his laser sword around. They had to edit out his noises in post-production.
8.Spielberg's War of the Worlds owes a debt to Revenge of the Sith
Lucas had hoped to get his mate Spielberg into the director's chair for Star Wars but it was not to be. The Jaws and Indiana Jones director did help out with Episode III however – including the Anakin and Obi-wan lightsaber duel, which was one of the high points of the prequels. Apparently Lucas took that knowledge of modern visual effects into his next big thing, War of the Worlds.
9. Episode III had more special effects shots than the first two prequels put together

These were the rolls that were used for the original dialogue recording, and the entire production recording that were done on the set."
