The Stepford Wives (1975)

In Bryan Forbes' great and shocking cautionary feminist sci-fi/horror cult tale (an adaptation of Ira Levin's novel):

• the scene of new Stepford, Connecticut suburban wives Joanna Eberhart and Bobbie Markowe (Katharine Ross and Paula Prentiss) noting suspiciously that their seemingly-perfect neighbor housewives only cleaned house and bowed to their husband's needs
• the garden party among the housewives and malfunctioning Carol's (Nanette Newman) quote: "I'll just die if I don't get this recipe!"
• the scene of the failed consciousness-raising session/discussion as the wives extolled the virtues of Easy-On spray starch
• Bobbie acting robotically in the kitchen while serving coffee to Joanna - being stabbed to test her humanity ("Do you bleed?") - and going berserk due to severed wiring (twirling and repeating monotonously): ("I was just going to give you coffee? How could you do a thing like that? I thought we were friends!")
• the startling scene in which Joanna came face to face with her semi-complete, sunken dark-eyed robotic double
• the image of the last haunting scene - all of the flowery-dress-wearing wives pushing their shopping carts in the supermarket
