Producer Jason Blum arrived at WonderCon over the weekend like a rock star, and was swarmed by a throng of fans. His Blumhouse Productions banner has gained a strong reputation as the next big voice in horror, delivering one hit after the next. While we saw the first sneak peeks from the convention center floor for Sinister 2 and Insidious Chapter 3 this past Saturday, we're now getting a TV spot for a completely new thriller experience with Unfriended.

Ushering in a possible new horror franchise, Universal Pictures' Unfriended unfolds over a teenager's computer screen as she and her friends are stalked by an unseen figure who seeks vengeance for a shaming video that led a vicious bully to kill herself a year earlier. After Universal executives saw a test screening of Unfriended terrify a test audience, the studio acquired the thriller that was developed and conceived by visionary filmmaker Timur Bekmambetov (Wanted, Abraham Lincoln: Vampire Hunter).

The April 17 release stars Shelley Hennig, Moses Jacob Storm, Renee Olstead, Will Peltz, Jacob Wysocki, Courtney Halverson and Heather Sossaman. Take a look at the latest terrifying footage:
