IMO The Best Sci-Fi Film ever made is 2001 A Space Odyssey
Blade Runner had some of the most powerful imagery I've ever seen in any movie. It's vision of a future city has often been imitated, but never surpassed. Something amusing: look at the visual readouts of the police car that Deckard gets into at the beginning of the movie--they are the same visual readouts of the Nostromo from Scott's classic,
Alien.
As for
2001, Kubrick was certainly a perfectionist. He hired aerospace engineers to design his spacecraft and equipment as approximate what would be reasonably available in the year 2001. One piece of trivia: the spacecraft seen orbiting the earth at the beginning of the Space Station sequence are actually orbital nuclear weapons platforms. Kubrick did not want to make too obvious, though, and invite comparison to his previous movie
Dr. Strangelove. Another piece of trivia: Kubrick and Arthur C. Clarke originally had the Discovery heading for Saturn. But budget constraints, and the fact that the special effects team couldn't make a realistic enough model of Saturn for Kubrick, forced the Discovery to stop at Jupiter.
If you love
2001, you owe it to yourself to check out these
forums. Among other things, this person makes extremely accurate models of
2001 spacecraft, including an 11'-long model of the Discovery for a recent Kubrick exhibition in Germany.
