2001: A Space Odyssey

A fateful night, 4 million years ago. A mysterious black slab arrives among a colony of apes; it seems to possess some kind of power to transmit intelligence, for later the apes devise a means of defending their waterhole against the encroachments of a neighbouring tribe.
2001. A similar slab has been found on the moon and has been discovered to be sending signals to Jupiter. A monumental space expedition is mounted, with astronauts Dave Bowman and Frank Poole operating a huge spaceship, their three colleagues in a state of hibernation and kept alive by the latest and most complex computer, Hal. The operation runs smoothly at first but then slowly, inexplicably, things begin to go wrong. The true nature of the mission is called into question and Discovery’s highly sophisticated onboard computer, the HAL-9000, appears to be sabotaging the crew he was designed to assist, jeopardizing not only the mission but the lives of everyone onboard.
