Jamie Lee Curtis Is Janet Leigh's Daughter
You know Janet Leigh pretty well, even if you think you don't: She's the one who gets shower-knifed to violin music in the classic scene from Psycho. Despite not appearing in a whole lot of horror movies (and barely appearing in Psycho itself), that 45-second shower scene established Leigh as one of Hollywood's greatest "scream queens." But not the greatest one: That would be her daughter, Jamie Lee Curtis.
You see, for a while Leigh was married to actor Tony Curtis (Some Like It Hot), and they had two daughters, Kelly and Jamie Lee. Both followed their parents into show business, and Jamie Lee's first big break as Laurie Strode in John Carpenter's Halloween (1978) not only kick-started her career, but also inaugurated the whole "empowered woman in terror" genre (Alien came out a year later). As Laurie, Jamie Lee didn't scream for a man to save her -- she actually fought back.
If she'd been in the shower, Norman Bates would have ended up a eunuch.
