Steven Spielberg has talked about the Indiana Jones DVD's and why we won't have to expect him to do director commentaries on any of his DVD's. Here's a report that TheForce.net has received from Donny Kennedy:

I am a cinema-television student at USC, and right now I have a class that analyzes the style of Steven Spielberg. He came in this past Wednesday, the 23rd, as a surprise guest speaker. (We were told it was going to be John Williams). Someone asked why he didn't do director commentaries on any of his dvd releases, and he remarked that he didn't like talking about his films on a soundtrack, because it takes away from the experience. Then he said that George Lucas had been begging him to put one on the Indiana Jones Trilogy dvd release, but he refused. He didn't say when, but it sounded like it was in the works. I was excited, but forgot to ask when. There's 350 people in the class, so it was hard to get a question in anyhow.
