TCM’s star of the month is Olivia de Havilland, who’s saluted each Friday night with a mini-retrospective of her movies. Tonight’s overview begins with this 1942 character study, in which she plays the sister of a scheming, vengeful, sexy woman – played by Bette Davis, in one of her most overtly vixenish roles – who sets out to steal her sister’s husband. And that’s just for starters.
