Announced earlier this year, Amityville 1974 will serve as a prequel to the original classic The Amityville Horror. With Casey La Scala attached to direct and principal photography set to begin this month, Bloody Disgusting has the film’s American Film Market sales art.

Deadline, who broke the initial news, details, “The focus shifts back to the traumatic murders that reputedly set the supernatural stage for the nation’s most notorious haunted-house legend. In November 1974, Ronald DeFeo Jr. shot all six members of his family in a spree killing that took on even more horrific hues a year later when a family bought the notorious property and lived in it for 28 days – a four-week window that became the core story of the Anson novel and its three big-screen adaptations.”

“This is a story that takes its jumping-off point from the true facts surrounding the Defeo tragedy,” La Scala said, “but also focuses on the human drama that took place inside a family as they were relentlessly stalked by a terrifying evil.”

Jeff Bowler, founding partner of Wonderfilm Media, and Shaun Redick (Get Out) will produce for Wonderfilm. Todd Garner (Tag) will also produce. Bret Saxon and Yvette Yates will Executive Produce.
