Most movie lovers don’t remember the 1962 film What Ever Happened to Baby Jane? for its psychological thrills. They remember the bitter real-lie feud behind the Warner Bros. production that made tabloid headlines. Bette Davis and Joan Crawford, two of cinema’s grand dames, co-starred in Baby Jane as aging sisters locked away in a crumbling mansion. Davis and Crawford’s careers were on the decline, and the film sought to make two of Hollywood’s greatest relevant once more. Crawford brought the project to Davis, but couldn’t stand the fact that she was later nominated for an Academy Award. Davis had her own axe to grind, after Crawford married the man she fell in love with during the making of a previous movie. That’s just the tip of it — but Ryan Murphy explores the relationship between stars during the making of Baby Jane in his FX series Feud, which premiers on Sunday, March 5.
