Keir Dullea in 2001: A Space Odyssey.

(1968, dir. Stanley Kubrick, 141 mins., USA/UK, PG)

A mind-bending, enigmatic sci-fi symphony, Kubrick's epic pushed the limits of film. Based on the writings of Arthur C. Clarke, the film traces a progression of man's relationship to tools -- from a bone used as the first weapon, to a supercomputer gone mad.

This film is part of the 2013 Winter Nights Film Series.
