The Conjuring 2

Valak’s first appearance was in this paranormal sequel. While not the central antagonist, the demonic nun steals every scene she’s in, so much so that she earned her spin-off. The movie combines supernatural thrills with emotional depth, making the nun's moments all the more unsettling.

The Devils Doorway

Shot in eerie black and white, this found-footage horror movie is set in a 1960s Irish Magdalene laundry. Two priests are sent to investigate a supposed miracle, but what they uncover involves demonic possession, abuse, and tormented nuns. It's gritty, atmospheric, and deeply unsettling.

The Nun

A spin-off of 'The Conjuring 2', this movie centres on a priest and a novitiate sent by the Vatican to investigate a Romanian abbey where a nun has taken her own life. They encounter the demon Valak, taking the form of a sinister nun. 'The Nun' is a gothic horror packed with jump scares, shadowy corridors, and unholy terror.

4/10

The Devils

A controversial and banned-in-several-countries classic by Ken Russell, 'The Devils' is based on the true story of the Loudun possessions in 17th-century France. It features scenes of religious hysteria, possessed nuns, and political corruption. Not for the faint-hearted, but undeniably powerful.

St. Agatha

Set in 1950s Georgia, a pregnant woman seeks refuge in a convent, only to find the nuns there enforcing harsh, cruel, and mysterious rituals. 'St. Agatha's leans into body horror and psychological torment, creating an atmosphere of oppressive fear.

Nun of That

For fans of grindhouse and campy horror, this movie is pure chaotic fun. A nun is gunned down and resurrected by God to battle evil with martial arts and machine guns. It’s ridiculous and irreverent — and definitely not for traditional horror fans.

Demons (2017) – aka The Crucifixion

Inspired by the true exorcism case of a Romanian nun, this film follows a journalist investigating the events leading to a priest’s arrest for murder. It’s atmospheric, disturbing, and raises the question: was it mental illness, or a real possession?

8/10

The Nun's Curse

This indie horror flick follows a group of paranormal investigators exploring a cursed prison where a vengeful nun was executed. Low-budget but with a creepy premise, it plays on religious guilt and vengeance from beyond the grave.

9/10

Agnes

Not your typical nun horror film, 'Agnes' explores the psychological and spiritual side of possession. Set in a remote convent dealing with a suspected demonic outbreak, it combines horror tropes with dark humour and emotional storytelling. A unique take on the subgenre.

10/10

The Other Hell

An Italian exploitation classic, 'The Other Hell' is a bizarre blend of religious horror, gore, and sleaze. A series of brutal murders at a convent leads to the discovery of demonic possession and secret experiments. It’s gory, twisted, and pure ‘80s cult horror.
