2001: A Space Odyssey

The story deals with a series of encounters between humans and mysterious black monoliths that are apparently affecting human evolution, and a space voyage to Jupiter tracing a signal emitted by one such monolith found on the moon. Keir Dullea and Gary Lockwood star as the two astronauts on this voyage, with Douglas Rain as the voice of the sentient computer HAL 9000 who has full control over their spaceship. The film is frequently described as an "epic film", both for its length and scope, and for its affinity with classical epics.
