Who's There?

About this list

Home is the one place we let our guard down, which is exactly why horror loves to violate it. The intruder who's already inside — hiding in the walls, living in the attic, watching from a room you thought was empty — turns the sanctuary of the house into a cage you've locked yourself into. This is a list for films where someone realizes they were never alone in their own home, and the call is coming from inside the house.
