2001: A Space Odyssey (1968) by Stanley Kubrick.

“I’ll never want to watch it on DVD or on TV. I have a 16mm copy that is very good. I could talk about it for three hours. The film is very important because all the form and all the content are merged. For example, in the music at the beginning, three notes, with an octave and a triad, are the same musical frequencies reflecting the geometry of the monolith: 1, 4, 9. Like the three steps of the film: apes, men and supermen. This is a mere detail, but there are other, very profound things that necessitate watching the film very closely. The film puts all visual cinematic forces in play, and there isn’t really a story.”
