The entire film was shot in a studio (in Arpajon). Jacques Saulnier, another of Resnais's longtime collaborators, provided elegant and sumptuous set designs, which together with the glamorous costumes designed by Jackie Budin complement the theatrical style of the acting, and frequent use of long camera shots enable a fluid staging of the musical numbers. Various cinematic devices are used both to intensify the characterizations (especially with close-ups and direct-to-camera asides), but also to distance the film spectator from the theatrical experience (e.g. dissolves to achieve characters' exits, overhead camera shots for some of the ensemble numbers).
