Stanley Kubrick at work on "2001: A Space Odyssey." The film, which was originally released on April 3, 1968, follows a group of astronauts on a journey to Jupiter with HAL 9000, a sentient computer. Though it was initially met with mixed reviews, "2001" is now widely considered a modern masterpiece.
