Hush...Hush, Sweet Charlotte is a 1964 American psychological horror thriller film directed and produced by Robert Aldrich, and starring Bette Davis, Olivia de Havilland, Joseph Cotten, Agnes Moorehead and Mary Astor in her final film role. It follows a middle-aged Southern woman, suspected in the unsolved murder of her lover from decades before, who is plagued by bizarre occurrences after summoning her cousin to help challenge the local government's impending demolition of her home. The screenplay was adapted by Henry Farrell and Lukas Heller, from Farrell's unpublished short story "What Ever Happened to Cousin Charlotte?"

Mary Astor was an American actress. Although her career spanned several decades, she may be best remembered for her performance as Brigid O'Shaughnessy in The Maltese Falcon (1941).
