The film was shot between May 21 and July 11, 1972. on a budget of 700,000 francs. Eustache called it a very hostile film, and it mostly consisted of dialogues and monologues about sex. Eustache says that the character Alexandre is "destroying three lead characters, but he is looking for it all along. After his voyage into madness and depression, he ends up alone. That's when I stop the film." Filming locations included Les Deux Magots Café, the Café de Flore, the Café le Saint-Claude, the Laennec Hospital, the Blue Train restaurant and inside various apartments on the Rue de Vaugirard and Rue Vavin. The film had no musical score and only used natural sounds and occasionally music played by the characters on phonographs, such as Wolfgang Amadeus Mozart, Edith Piaf, Marlene Dietrich and Deep Purple.
