SFX master Steven Boyle’s effects work has been seen in 2005’s King Kong, Love and Monsters, Bait, What We Do in the Shadows, The Matrix trilogy, and so much more. Now, Boyle is set to make his feature directorial debut, The Demon Disorder, a new upcoming Shudder original with an eerie new trailer.

The film, described as a demonic family drama, will make its exclusive streaming debut on Shudder in Fall 2024. 

Watch the new trailer below to get acquainted with Graham, Jake, and Phillip Reilly, whose lives are upended by a long-buried family secret. As their pasts collide, their late father’s garage becomes the eerie epicenter of supernatural revenge. Boyle puts his SFX background to good use if these goopy, gory, demonic images are anything to go by.

The Demon Disorder  “centers on Graham, a man haunted by his past since the death of his father and the estrangement from his two brothers. Jake, the middle brother, contacts Graham, claiming that something is horribly wrong: their youngest brother, Phillip, is possessed by their deceased father. Graham reluctantly agrees to go and see for himself. With the three brothers back together, they soon realize they are unprepared for the forces against them and learn that the sins of their past will not stay hidden. But how do you defeat a presence that knows you inside and out? An anger so powerful it refuses to stay dead?”

John Noble (The Conjuring: The Devil Made Me Do It, The Lord of the Rings Trilogy), Charles Cottier, Christian Willis, Dirk Hunter, and Amy Ingram star in the family horror film.

“We are thrilled that The Demon Disorder has reached its final resting place with our friends at Shudder,” said Boyle.  “It’s a community and fanbase that we hold in the highest esteem, and we couldn’t be happier to be on this journey with them!”

“After years of creating a range of elaborate visual experiences through his work as a special effects designer on iconic films, we’re thrilled to give Steven Boyle a platform for his feature length directorial debut with The Demon Disorder,“ said Samuel Zimmerman, Head of Programming for Shudder.  “Full of impressive body horror that fans have come to expect from this master of effects, Boyle’s film is an engrossing story about breaking generational curses that viewers will find both unsettling and amusing.”

Written and directed by Boyle, along with Toby Osborne (PINDAM) as writer, The Demon Disorder is produced by Boyle and Ally Muller and executive produced by Michael Spierig and Peter Spierig.
