Elizabeth Cullen Is Ushered Through an Ominous Miracle Cure in New ‘Diabolic’ Image [Exclusive]

So-called miracle cures are often sketchy, though none may be more so than the one undergone by Elizabeth Cullen in the horror film Diabolic. The blood-curdling Australian film isn’t set to release until February, but before then, we’re excited to include the film as part of Collider’s Exclusive Preview week for upcoming winter film and television titles. We have a new image that spotlights Cullen’s Elise, who appears to be in the middle of receiving her treatment. Bathed in a moody orange, almost ethereal glow from the candles, however, it looks more like she’s taking part in an ominous ritual than anything that could save her from her ailments.

Diabolic centers on “a religious cult, a troubled young woman, hallucinogenic therapy, and an evil that refuses to die.” It follows Elise, who, in search of anything that can quell her unexplained and seemingly incurable blackouts, turns to the Fundamentalist Latter Day Saints for help. She hopes their healing ritual will be exactly what she needs, but the miracle cure quickly sours into a waking nightmare when they unwittingly unleash the vengeful spirit of a cursed witch who’s dead set on claiming Elise’s body as the vessel for her wicked power. The demonic entity plans to use her newfound opportunity to get revenge on all who wronged her in life.

Cullen is perhaps best known for her work on the small screen, between Paper Dolls, Last King of the Cross, and her key role on The Bureau of Magical Things. She also enjoyed a small part in Baz Luhrmann‘s Elvis, though Diabolic will mark her first crack at leading a movie. Joining her in the possession flick are 9-1-1 alum John Kim and Outer Banks star Mia Challis. Though reviews are few ahead of its wide release, the film was a smash hit at the Adelaide Film Festival last month and was one of the few titles selected for an encore screening due to its popularity with attendees.

Who Is Behind ‘Diabolic’?

Behind the camera for Diabolic was Daniel J. Phillips, who made his directorial debut back in 2019 with the horror mystery film Awoken. In the time since, he also penned a segment for the spine-chilling anthology The Red Book Ritual. He co-wrote the screenplay for his latest with Mike Harding and Ticia Madsen, with Grant Hardie, Vasili Papanicolou, Mark Patterson, and Silvio Salom all serving as producers. Australia has a rich history of frights that have crossed over to U.S. audiences, like The Babadook and Talk to Me, and there’s hope that Phillips’s Diabolic can be the next to make waves stateside.

Diabolic arrives in the U.S. in February 2026. Check out our exclusive image above and stay tuned here at Collider for more throughout the week as we share more winter previews.
