Day for Night is a 1973 romantic comedy-drama film co-written and directed by François Truffaut, starring Jacqueline Bisset, Jean-Pierre Léaud and Truffaut himself. The original French title, La Nuit américaine ("American Night"), refers to the French name for the filmmaking process whereby sequences filmed outdoors in daylight are shot with a filter over the camera lens (a technique described in the dialogue of Truffaut's film) or also using film stock balanced for tungsten (indoor) light and underexposed (or adjusted during post-production) to appear as if they are taking place at night. In English, the technique is called day for night.

Plot

Day for Night chronicles the production of Je Vous Présente Paméla (Meet Pamela, or literally I Introduce You to Pamela), a clichéd melodrama starring aging screen icon Alexandre, former diva Séverine, young heartthrob Alphonse and British actress Julie Baker, who is recovering from both a nervous breakdown and the controversy over her marriage to her much older doctor.
