Hush...Hush Sweet Charlotte (1964)

A succulent slice of Grand Guignol conceived as a follow-up to the success of "Whatever Happened to Baby Jane" and meant to reteam Bette Davis and Joan Crawford; when the latter cried off, her role was taken by the slightly younger Olivia de Havilland.  It begins nearly forty years earlier when Davis is involved with her married lover played by a surprisingly pretty, young Bruce Dern, who is brutally murdered.  Her father in this pre-credit sequence is played by Victor Buono (who was her would-be suitor in Baby Jane).  Flash forward to the house-bound Davis considered loco and guilty by all and being driven to breaking point by her cousin, De Havilland.  Add on a splendid cast which includes Joseph Cotton, Agnes Moorehead, Cecil Kellaway and Mary Astor, plus an early role for George Kennedy, and you have an enduring classic.  I love it.
