1. '2001: A Space Odyssey'
A little over a year before men landed on the moon, Stanley Kubrick released a movie about a group of astronauts forced to battle their super intelligent computer while on a space mission. The film actually begins with a group of apes in the distant past that come across a mysterious monolith that speeds up their evolutionary process, before skipping thousands of years into the future. The pacing is slow by today's standards and the final sequence seems like a long and confusing acid trip, though Kubrick knew exactly what he was doing, even if people are still arguing over what exactly that was.
