Steven Spielberg a "Guest Director" on Episode III?
I heard that George Lucas allowed his friend Steven Spielberg to design some of the action sequences, including Yoda's duel with Darth Sidious, and Obi-Wan's fight with General Grievous. Spielberg also consulted on other scenes, such as the climactic battle between Obi-Wan and Anakin.
I thought Lucas was pretty nice allowing Spielberg to work in some part of the movie since they are best friends. I heard a few years ago that Lucas refused Spielberg in directing the one of the Star Wars movies. Spielberg said that Lucas was too possessive of his blockbuster space saga to let anyone else have a try.
"I've asked him. He won't let me do one," said Spielberg. "I wanted to do one 15 years ago and he didn't want me to do it. I understand why - Star Wars is George's baby. "
