Check out this teaser trailer for Grim Night based on a spec script penned by first-time feature writers Brandon Bestenheider and Allen Bey and produced by Bryan Bertino (The Strangers) and Adrienne Brittle. According to Deadline, there was a heated battle over the script among the big movie studios and in the end Universal Pictures purchased it making a deal “in the high six- or seven-figure range.” The plot is creepy all the way to its core, and horror fans are eating this up. The teaser trailer introduces us to a world where there is one day every year when creatures known as “Grims” terrorize and murder people on Earth. The scariest bit is that the Grim attacks are extremely violent and senselessly random. The movie will focus on a family in small town America defending themselves against the hooded Dementor-like Grims. Since it’s so early in development, there is no telling how much the final product will look like the teaser embedded above. If the young writing duo and veteran producers are smart, they won’t deviate too far from what they already have. The scary, apocalyptic, gritty and viral-video feeling here is very reminiscent of recent flicks like Paranormal Activity, District 9, and Bertino’s own The Strangers. More as this story develops. Oh, and good luck sleeping tonight after watching this doozy.
