DIABOLIC Trailer Unleashes a Faith-Fueled Reformed Mormon Horror Nightmare
The trailer for Diabolic has arrived, and it’s tapping into a deeply unsettling mix of faith, trauma, and demonic influence. Directed by Daniel J. Phillips, whose previous work includes Awoken, the film leans hard into psychological horror while pushing its supernatural elements to some genuinely disturbing places. What unfolds looks intense, uncomfortable, and very eager to crawl under your skin.
At the center of the story is Elise, played by Elizabeth Cullen, a woman spiraling as blackouts and fractured memories begin to dominate her life. The trailer keeps us locked in her perspective as reality starts slipping through her fingers.
Elise doesn’t know what’s real anymore, and neither do we. Desperate for answers, she reaches back to a past she thought she’d left behind, reconnecting with members of the Mormon church she once belonged to.
Instead of therapy or medical help, Elise is guided toward a group of so-called healers who promise spiritual relief. What follows is a series of rituals that feel wrong from the moment they begin.
Strange drinks are consumed. Disturbing ceremonies unfold. The elders ultimately claim they’ve cleansed Elise of an evil presence, but the trailer makes it very clear that something far worse has been unleashed.
Blood-soaked imagery, vicious jump scares, and haunting visuals, including some seriously unsettling long nails, push the horror into overdrive as the demon’s grip tightens.
Cullen is supported by a cast that includes John Kim, Mia Challis, Robin Goldsworthy, and Genevieve Mooy.
After releasing in Australia toward the end of last year, Diabolic quickly started pulling in strong reactions from audiences who were shaken by its relentless tension. With filmmakers like Danny and Michael Philippou making waves with Talk to Me and Bring Her Back, Australia continues to prove it’s a serious powerhouse for modern horror.
Phillips also co-wrote the screenplay alongside Mike Hardin and Ticia Madsen, while producing. The movie comes from Brainstorm Media, which has been steadily building a reputation for backing edgy genre projects, including Sleepwalker starring Hayden Panettiere and the Kiefer Sutherland-led Tinsel Town.
If the trailer is any indication, Diabolic is the kind of film that wants to rattle your beliefs, mess with your sense of reality, and leave you questioning whether faith can save you or doom you.
There is no release date for the film yet.
