The Containment - FAQs
What is The Containment about?
The Containment follows a young woman named Caroline who becomes possessed by a sinister entity. Her mother, doctors, and an exorcism expert all fail to free her — until a nun steps in and raises a doubt far more unsettling than the possession itself, blurring the line between faith and fear.
What doubt does the nun reveal in The Containment?
Sister Esperanza, played by Fernanda Romero, introduces a chilling question: is Caroline truly possessed by a demon, or is something else entirely at work? This twist reframes the entire story, suggesting the real horror may not be supernatural at all — making it arguably more terrifying than any demon.
Who are the main actors in The Containment?
The cast is led by Gia Hunter as Caroline, the possessed girl at the center of the story. She's joined by Jack Gouldbourne, Fernanda Romero as Sister Esperanza, Alice Coulthard, Roger Cudney, Edmund Dehn as Father Robert, and several others rounding out this supernatural ensemble.
Is The Containment based on a true story?
The Containment does not appear to be based on a specific true story. It's an original supernatural horror film from Mexican directors Jack Zagha Kababie and Yossy Zagha, drawing on familiar possession mythology while weaving in a narrative twist that questions the nature of the supernatural events depicted.
Who directed The Containment?
The Containment was co-directed by Jack Zagha Kababie and Yossy Zagha, who also co-wrote the screenplay alongside David Desola. The duo also served as producers on the film, which was produced under the Avanti Pictures banner in Mexico.

The Containment had its initial release on June 5, 2025, in Russia with an 18+ rating. The film is a Mexican production spoken in both English and Spanish, bringing an international flavor to its supernatural horror premise.
What are similar movies to The Containment?
If The Containment grabs you, check out The Exorcist (1973), The Exorcism of Emily Rose (2005), Prey for the Devil (2022), 13 Exorcisms (2022), and Huesera: The Bone Woman (2023). These films share the same unsettling blend of demonic possession, religious dread, and psychological horror.
How long is The Containment?
The Containment runs for 88 minutes — just under an hour and a half. It's a tight, focused runtime that keeps the tension coiled throughout, giving the possession narrative and its shocking twist little room to breathe, which works very much in the film's favor.
