Entr'acte (1924) is a short film directed by René Clair, which premiered as an entr'acte for the Ballets Suédois production Relâche at the Théâtre des Champs-Élysées in Paris. Relâche is based on a book and with settings by Francis Picabia, produced by Rolf de Maré, and with choreography by Jean Börlin. The music for both the ballet and the film was composed by Erik Satie.
For this production, the Dadaists collaborating on the project invented a new mode of production: instantanéisme. The complete film takes about 20 minutes using such techniques as watching people run in slow motion, watching things happen in reverse, looking at a ballet dancer from underneath, watching an egg over a fountain of water get shot and instantly become a bird and watching people disappear.
The cast included cameo appearances by Francis Picabia, Erik Satie, Man Ray, and Marcel Duchamp. The conductor of the orchestra at the premiere was Roger Désormière. In this (definitive) edition the soundtrack was conducted in 1967 by Henri Sauguet.
