1999 was cool, I remember seeing it a few times as a kid, and was like, whoa, what is that??? Unlike anything else on TV at the time.

Clearly it was influenced by Stanley Kubrik's masterpiece 2001: A Space Odyssey.
Watching that movie as an adult, I am struck by how incredibly prescient it was in terms of thinking about the future. Of course, there was some linear prediction-- moon shot, Pan Am, Bell Telephone, all of course would feature heavily in the future! Even though that didn't really happen, it still feels like it could have. They even had Ipad like devices... What blows my mind is the thought of someone going into a dark theater in 1969, seeing that movie, and walking out... into 1969 America. I still can't comprehend it. I wonder what a movie would look like today that had that sort of future view.
