The thoughtful, intercut discussion with all three directors touches on many topics, including the role of technology in film (Lucas has a few things to say) and also the preservation of the movies, which is a cause these three have brought to prominence since then. Spielberg notably talks about looking into the original elements for JAWS and finding them in a shambles. Cut to last year, when a definitive Blu-Ray restoration of JAWS was released. Spielberg also promises that there will never ever be an ET sequel...and he's actually kept that promise. Lucas, on the other hand, promises three new STAR WARS films and most of us wish he didn't keep that promise. :)
Late in the show, they all talk about the future of HDTV which was just making it's first impression with some experimental sets. There is even a widely expressed concern that people will stop going to the movies with the home movie experience being the same as at home. But Lucas aptly predicts that the movie theatres will be home to more spectacles and personal films will gravitate towards the home screen.
