While MALICIOUS is of the tribe of FATAL ATTRACTION, I think other commentators here have overlooked its obvious progenitor. The scenario of the final section -- the psycho becomes the girlfriend's roommate under an assumed name -- is a direct lift from PLAY "MISTY" FOR ME. In this version, though, there are two huge improbabilities: A). Melissa is a notorious fugitive of wealthy background who did in her own dad -- it is incredible that Laura has never seen her picture; and B.) when our hero learns Melissa is in Laura's apartment, instead of calling the police immediately, he goes hurling across San Francisco on a motorcycle, unarmed, in the rain. I hope I never need him to rescue me.
