Backrooms wouldn’t exist without Robin Williams’ underrated psychological thriller

As Obsessioncontinues to be a surprise box office juggernaut, the new horror film Backrooms has followed that up with the largest-ever opening weekend for an original horror movie. Backrooms is about a lonely, frustrated furniture store owner who discovers an invisible doorway in the downstairs of his business. Once he steps through it, he finds a seemingly endless series of office-building like rooms with familiar-yet-distorted items and a bizarre entity within.
