2001

The first spoken word is almost a half hour into the film, and there's less than 40 minutes of dialogue in the entire film. Much of the film is in dead silence (accurately depicting the absence of sound in space), or with the sound of human breathing within a spacesuit. Kubrick's sci-fi experiment intended to present its story almost purely with visual imagery and auditory signals with very little communicative human dialogue (similar to what was attempted in the surreal, fragmented, non-narrative imagery of the Qatsi trilogy - from 1983-2002, from Godfrey Reggio). All scenes in the film have either dialogue or music (or silence), but never both together.
