Chiller's all-new original special, "Real Fear: The Truth Behind the Movies" premieres Sunday, March 11 at 8pm.

The show will uncover the terrifying real-life stories that inspired some of the most popular horror films of all time!

Paranormal investigator Katrina Weidman ("Paranormal State"), along with three of her colleagues, reveal the secrets behind four iconic movies: "Poltergeist," "The Amityville Horror," "Silent Hill" and "The Mothman Prophecies."

The special also features exclusive eyewitness accounts from Lucille Herrmann, whose family made national attention in 1958, when they experienced unexplained poltergeist activity in their house in Seaford, NY (later influencing the popular film); and Christopher Lutz, the youngest member of the Amityville family who lived through the terrifying paranormal events in the infamous Long Island home.
