A perfect movie for the digital age, A.I. finds a natural home on DVD. The purity of the picture, its carefully composed colour schemes and the multifarious sound effects are accorded the pin-point sharpness they deserve with the anamorphic 1.85:1 picture and Dolby 5.1 sound, as is John Williams’s thoughtful music score. On the first disc there’s a short yet revealing documentary, “Creating A.I.”, but the meat of the extras appears on disc two. Here there are good, well-made featurettes on acting, set design, costumes, lighting, sound design, music and various aspects of the special effects: Stan Winston’s remarkable robots (including Teddy, of course) and ILM’s flawless CGI work. In addition there are storyboards, photographs and trailers. Finally, Steven Spielberg provides some rather sententious closing remarks (“I think that we have to be very careful about how we as a species use our genius”).
