Le Chat movie review & film summary (1975)
Years ago, Clemence was an acrobat, lithe and beautiful and the heroine of the circus. Julien was a typesetter, young and sturdy and in love with her. She had a bad fall and broke her leg, and would limp for the rest of her life. So she left the circus and married Julien, and for a long time, their marriage was a perfect one. But, so slowly that perhaps the stages of the change were never marked, their love turned to a terrible hatred. And yet they remained so intimate they could almost read each other's minds.
