In 1924, a film named Entr'acte premiered as 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 Borlin. This short film was directed by René Clair with the music for both the ballet and the film composed by Erik Satie (the last music he composed). For this production, the dadaists collaborating on the project had invented a new flavor of dada or surrealism: 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 of Francis Picabia, Erik Satie, Man Ray and Marcel Duchamp. The conductor of the orchestra at the premiere was Roger Désormière.
