BLACK WIDOW (1987)

Catherine (Theresa Russell) is a beautiful young woman who has married and murdered three millionaires for their insurance.  With each one she changes her appearance, dons a new name, and spends months researching the man's personal and professional life, boning up on whatever interests he has until she can discuss them like her own.  She makes each death look like accident or illness, and vanishes soon as she collects her inheritance - seemingly unstoppable until ambitious Justice Dept. investigator Alex Barnes (Debra Winger) stumbles upon a clue pointing to one of the deaths as murder - and becomes obsessed with Catherine when she just misses preventing her latest kill.  Taking a leave from her job, Alex trails Catherine to Hawaii, ingratiating herself into Catherine's world even while trying to find a way to stop her.  One of the best "guilty pleasures" ever; one you'll watch over and over again, thanks to the blistering chemistry between Winger and Russell.  Surprising, just how good this is.
