The film is based on instructions for a cinematic alphabet given by Marcel Duchamp in a brief recording of the text with the same title. The text was written in 1912 (!) and recorded in 1967. The record label SubRosa released this sound fragment during the 90s.

‘(…) Menke illustrates Marcel Duchamp’s theory about language of photographs and films. Unrecognisable close-ups of random objects can be given a meaning that can be translated into words. We hear the voice of Duchamp reading from A l´infinitf: a text from 1920 in which he has laid down his theory.’ (from IMPAKT Festival for audiovisual arts 15-19 may, Utrecht, Netherlands. Screened in programme ‘Panorama 13 Ritual’)
