For whatever reason, filmmakers and moviegoers alike seem to find twins inherently creepy. Would The Shining have been as menacing if it were just another child trying to lure Danny to his death? No – for some reason what’s particularly terrifying is the image of those two identical girls waving and beckoning, “Come play with us, Danny…”

It’s as if they’ve conspired. You’re outnumbered. There’s the idea that they’re doppelgangers able to fool the rest of us, that or they are two half beings unable to live without the other and yet perhaps quietly desperate to try.

We’ve enlisted the help of Senior Twin Correspondent Joy Madden (she’s Hope’s evil twin, FYI) to puzzle through the best in twin horror. Unlike The Shining, though, twins are the centerpiece of these films and it is their very twin-ness that drives the story.
