Quadrille (1938)

A sparkling four-way affair overflowing with dialogue that showcases writer-director Sacha Guitry’s wit, Quadrille stars Guitry as a magazine editor whose longtime girlfriend (whom he hopes to make his fiancée) is uncontrollably drawn to a handsome American movie star. Meanwhile, a discerning reporter (Jacqueline Delubac) watches from the sidelines with amusement and provides the final corner of this romantic rectangle.
