2001: A Space Odyssey (see description)

Directed by Stanley Kubrick. Novel written by Arthur C Clarke. Distributed by Metro-Goldwyn-Mayer. No copyright infringement intended. Uploaded as an incentive to buy original copy. I think the most profound scene in movie history. The bone, (weapon of pre-historic man) thrown skyward, gives way to a similar shaped 'nuclear weapons platform', (weapon of modern man) in Earth orbit. In a fraction of a second, the viewer has jumped millions of years in the evolution of mankind.
