This was supposed to be a rematch between Bette Davis and Joan Crawford following their success in Whatever Happened to Baby Jane?, but early in the production Joan threw in the towel, so Olivia de Havilland strapped on the gloves. Olivia wasn't as combative on set, and she and Bette got on, but she's well cast as a ruthless villain operating behind a mask of respectability.
Charlotte (Davis) was assumed to have cut off the head and hands of her married beau back in 1920s Louisiana. Now she's a rich old spinster, going crazy. Her cousin (Olivia) aims to gaslight her into a madhouse so she can profit from the property development taking over Miss Charlotte's plantation. There's an audacious climax which will stun anyone who's never seen Les Diaboliques.
It's the sort of sixties family horror that traded on re-situating the great stars of the golden age in a kooky contemporary context. Joseph Cotten supports and there's an appearance from Mary Astor. Agnes Moorhead does some scene stealing as Charlotte's cranky maid. But they are all ultimately merely context to Bette Davis' self-parodic scenery chewing.
It's Southern Gothic, with plenty of atmosphere and genre archetypes and gossiping townsfolk. There is a house full of shadows and the big scenes are scored with thunderstorms rattling the blinds. It's mainly a battle of the divas between Bette and Olivia, but credit to director Robert Aldrich for keeping such a ripe confection so digestible. And it's a lot of fun for fans of the stars.
