Australian supernatural horror film Diabolic is heading to the UK and Ireland later this month, with Lightbulb Film Distribution confirming the film’s release on Blu-ray, DVD and Digital from 25 May.
Directed by Daniel J. Phillips, best known for horror feature Awoken, the chilling new release promises a tense blend of psychological terror, cult horror and supernatural suspense.

What Is Diabolic About?
The film follows Elise, a young woman haunted by terrifying blackouts who returns to the isolated religious compound where she was raised. As she begins uncovering disturbing secrets linked to her past, an ancient ritual awakens the vengeful spirit of a cursed witch.
The official synopsis teases a dark and atmospheric horror experience packed with dread, mystery and jump scares — making it one for fans of slow-burn supernatural cinema.

Genre fans may recognise cast members from projects including Clickbait, The Babadook and The Little Things.
