Played By: Laura Harring
Movie: Mulholland Drive (2001)

Rita, a dead-ringer for Gilda, another femme fatale on this list, is notable in that she has all the mystery and intrigue of a classic femme, but in this case, those charms have a woman under pressure, namely Betty Elms (Naomi Watts). Betty arrives to stay at her aunt’s house only to find Rita, who's suffering from amnesia, having just survived both her attempted murder and a car crash, with a purse full of stacks and a mysterious key. Which is to say, she can only be trouble.
