Deadline and Shocktillyoudrop pick up another story from the tracking boards reporting that Universal Pictures has completed a pre-holiday acquisition of a spec script written by The Strangers writer/director Bryan Bertino.

Here’s the plot crunch sent around town: “Found footage thriller centering on three cameras that are given to three separate households on the same night with instructions to keep filming if they want to live, but as the night wears on, the characters are pulled into a deadly confrontation with each other at the behest of their unseen tormentor.”

The project was acquired to be produced by Blumhouse’s Jason Blum, and Marc Platt and Adam Siegel of Marc Platt Productions. Bertino and his Unbroken Pictures partner Adrienne Biddle will also be producers. Blum and Platt have term deals at the studio. Blum is producer of the Paranormal Activity films.

Like Paranormal Activity, the Bertino spec was being sent around town under the title Mockingbird, and is based on “found footage.” Bertino is not aboard to direct the film. Blumhouse just wrapped the Rob Zombie-directed The Lords of Salem, as well as the Ethan Hawke-starrer Sinister for Summit Entertainment and is producing the ABC series “The River.”
