Filming began on 17 August 1959. Godard met his crew at the Café Notre Dame near the Hôtel de Suède and shot for two hours until he ran out of ideas. Coutard has stated that the film was virtually improvised on the spot, with Godard's writing lines of dialogue in an exercise book that no one else was allowed to see. Godard gave the lines to Belmondo and Seberg while having a few brief rehearsals on scenes involved, then filming them. No permission was received to shoot the film in its various locations (mainly the side streets and boulevards of Paris) either, adding to the spontaneous feel for which Godard was aiming. However, all locations were selected before shooting began, and assistant director Pierre Rissient has described the shoot as very organized. Actor Richard Balducci has stated that shooting days ranged from 15 minutes to 12 hours, depending on how many ideas Godard had that day. Producer Georges de Beauregard wrote a letter to the entire crew complaining about the erratic shooting schedule. Coutard said that de Beauregard bumped into the director at a cafe and the two got into a fist fight on a day that Godard had called in sick.
