I'm excited to be able to see Attack of the Clones digitally projected at Cinerama opening day (tomorrow I guess!). This will be my first experience with digital projection, which George Lucas has been pushing for hard. There are two popular digital projection systems: Boeing and Texas Instruments. Cinerama will use the Boeing system. The number of theaters digitally projecting Episode II in the United States is low--something like twenty or so.
Roger Ebert, long a fan of film over digital projection, admits that based on his firsthand experience, the digital projection of Clones looks superior. He theorizes it's because Clones was shot digitally so it didn't need to be translated to film in the digital projection system (the same reason audiophiles hate to see
signals translated from analog to digital or vice versa--something is always lost in the translation, as everyone knows).
