Duelle

The Queen of the Night battles the Queen of the Sun over a magical diamond that will allow the winner to remain on Earth, specifically in modern day Paris.

Marilù Parolini originally came from Italy, but moved to France where she got mixed up in the French New Wave movement. As part of that, she wrote this "experimental fantasy" with her husband, director Jacques Rivette. At this point, he had just finished "Celine and Julie Go Boating" (1974), which is among his best-known films today.

Star Juliet Berto also came out of "Boating", though she is more generally associated with the work of Godard. Co-star Bulle Ogier is more often seen as a Rivette regular, though the two appeared in many of the same films. Ogier also has the distinction of being in Luis Bunuel's "Discreet Charm", which is widely loved by critics (though I was less than impressed).
