17. Carol Lynley in Once You Kiss a Stranger (1969)
Okay, Once You Kiss a Stranger may be a rip off of Hitchcock's Strangers on a Train but let us ask you one thing: Did Hitchcock ever have Lynley holding a spear and wearing a skimpy bikini? The answer is, unfortunately, no. Lynley perfected her "come-hither" appeal, luring men in to do her dirty work, and helped reintroduce the sexy femme fatale to the silver screen. The bikini-clad starlet became the new standard for a devious, murderous woman in film.
