The trailer for ‘demonic family drama’ The Demon Disorder, has been released this week, ahead of the Australian horror film’s theatrical release in August 2024.

The dark story follows three brothers who are reunited after the youngest is possessed by their deceased father.

The Demon Disorder is the feature directorial debut of special effects master Steve Boyle (The Matrix trilogy, The Hobbit, King Kong, Daybreakers), and stars John Noble, Charles Cottier, Christian Willis and Dirk Hunter.

The film is written and directed by Boyle, along with Toby Osborne (Pindam) as writer. It is produced by Boyle and Ally Muller and executive produced by Michael Spierig and Peter Spierig (Daybreakers, Undead, Predestination). Peter Spierig is also credited with the music.


The story centres 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 realise 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?’
