HBO Max - The platform recently added Anatema to its catalog, and the film immediately caught the attention of horror audiences by merging religious terror, investigative suspense and catacomb exploration — a combination that raises the stakes for viewers seeking darker streaming offerings.
- In short: Anatema sends Leonor Watling’s nun-architect back to a Madrid temple built over catacombs, where an ancient malignant presence forces a dangerous investigation.
Where the mystery begins beneath a Madrid church
Directed by Jimina Sabadú and starring Leonor Watling, Anatema follows Juana, a religious woman trained in architecture who returns to restore an old temple in Madrid built atop an extensive subterranean network. For background on the cast and crew, see IMDb for credits and filmography.
The plot unspools from a childhood trauma — Juana witnessed an inexplicable event during her brother’s communion — into a restoration that uncovers something older and more dangerous than local legend.
"The space hides something far older than simple religious legend — a malignant presence in the depths that predates known stories and threatens to spill beyond the church."
Tone, impact and why it matters for viewers
Anatema leans on atmosphere in its first half, using Gothic architecture, narrow corridors and silence to build unease before shifting toward more explicit visual sequences later in the film. That tonal pivot blends slow-burn dread with elements of adventure-horror, which may divide fans of tightly psychological scares versus spectacle-driven fright.

Beyond scares, the film taps into a long-running subgenre where faith and architecture become characters — a line of storytelling that has proven resilient on streaming services, attracting viewers who favor atmospheric, location-driven horror.
