Duelle (Une quarantaine) is a 1976 French experimental fantasy drama film directed by Jacques Rivette. The main title is a neologistic feminine form for the noun "duel". The director-assigned¹ English title is Twhylight, a combination of "twilight" and "why". The film stars Juliet Berto as the Queen of the Night who battles the Queen of the Sun (Bulle Ogier) over a magical diamond that will allow the winner to remain on earth, specifically modern-day Paris.
