2001: A Space Odyssey is a 1968 epic science fiction film produced and directed by Stanley Kubrick, who co-wrote the screenplay with Arthur C. Clarke.

Plot
In a prehistoric veld, a tribe of hominins is driven away from a water hole by a rival tribe, and the next day finds an alien monolith. The tribe learns how to use the bones of dead animals as weapons and, after a successful first hunt, uses them to drive away the rival tribe. Millions of years later, Dr Heywood Floyd, Chairman of the United States National Council of Astronautics, travels to Clavius Base, an American lunar outpost. During a stopover at Space Station Five, he meets Russian scientists who are concerned that Clavius seems to be unresponsive. He refuses to discuss rumours of an epidemic at the base. At Clavius, Floyd addresses a meeting of personnel, stressing the need for secrecy regarding their newest discovery. His mission is to investigate a recently found artefact, a monolith buried four million years earlier near the lunar crater Tycho. As Floyd and others examine and photograph the object, it emits a high-powered radio signal.
