Based on The Forbidden Garden by Ursula Curtiss, this movie was produced by Robert Aldrich, America’s finest purveyor of hagsploitation. After all, this is the same man who made What Ever Happened to Baby Jane? and Hush…Hush, Sweet Charlotte.
This time, your crazy older women are played by Geraldine Page and Ruth Gordon, despite Page only being 43 at the time of filming.
Claire Marrable (Page) is the widow of a prominent businessman who died in debt, giving her only a briefcase and his collections of butterflies and stamps in death. Upon moving to Tucson to be closer to her nephew George, Claire begins her career of serially killing housekeepers.
Soon, she begins a cold war with both her newest housekeeper Alice Dimmock (Gordon) and Harriet Vaughn, a much younger widow. Peter Bonerz, who was Dr. Jerry on the original Bob Newhart Show is in this, too.
Lee H. Katzin — who directed the first episodes of Man from Atlantis and Automan — replaced Bernard Girard (Dead Heat on a Merry-Go-Round) as the director of this movie after only one month of filming.
At one point, Aldrich announced that he would make a third What Ever Happened to… film. What Ever Happened to Dear Elva?, based on the novel Goodbye, Dear Elva by Elizabeth Fenwick, was planned but never made.
