I rented Episode III earlier in the week and watched it again. Definitely, the best of the newer trilogy. I liked seeing the deleted scenes and hearing George Lucas's commentary. They let the graphic supervisors discuss their scenes as well. In the opening space battle, one pointed out they actually had a kitchen sink fly out of an exploding ship and hit another ship.
Another neat feature on the bonus DVD was an analysis of 49 seconds of the light saber duel at the end. The documentary makers showed how all the people involved in the making of that section of the film. Let's just say, a lot of people are involved! It looks like a lot of work on the movie was done in Australia. I thought they would have done a majority of the work in California but apparently not. It was also interesting that they traveled to China to take pictures of the hills there for the Wookie planet.
One other thing that I learned was that the actors are in front of a lot of green and blue screens. It must be quite hard acting when you have no idea what your surroundings look like. They seemed to have had a lot of computer generated backgrounds. Also they put the heads of actors on stand in doubles.
