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 The screenplay was adapted by Henry Farrell and Lukas Heller, from Farrell's unpublished short story "What Ever Happened to Cousin Charlotte?"

Victor Charles Buono was an American actor, comic, and briefly a recording artist. He was known for playing the villain King Tut in the television series Batman (1966–1968) and musician Edwin Flagg in What Ever Happened to Baby Jane? (1962), the latter of which earned him Academy Award and Golden Globe Award nominations. He was a busy actor from his late teens until his death at the age of 43 and, with his large size and sonorous voice, he made a career of playing men much older than he was.
