2001: A Space Odyssey by Stanley Kubrick, 1968. A film that lingers in memory; in his own words: "2001 is a nonverbal experience; out of two hours & 19 minutes of film, there are only a little less than 40 minutes of dialogue. I tried to create a visual experience, one that bypasses verbalized pigeonholing & directly penetrates the subconscious with an emotional & philosophic content. To convolute McLuhan, in 2001 the message is the medium." http://www.imdb.com/title/tt0062622/
