Terrifier 3’s release window has been confirmed by the director following Terrifier 2’s massive success. From low-budget horror director Damien Leone, the series originated from the director’s 2011 short of the same name before being adapted as part of the 2013 anthology All Hallows' Eve and solo 2016 movie. That film’s follow-up, Terrifier 2, was met with unprecedented box office success as audiences came in droves to see the slasher thrills of Art the Clown strike again.
