Duelle (Une quarantaine) is a 1976 experimental fantasy drama directed by Jacques Rivette. The main title is a neologistic feminine form for the noun "duel." The director-assigned English title is Twhylight, superimposing "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.
