Wolf at the Door Gothic Horror Film in the Works at Concord

Concord Originals, the film and TV division of music and theatre company BMG, is developing a feature adaptation of Wolf at the Door, a supernatural gothic horror tale based on the play by Marisela Treviño Orta. Argentinian filmmaker Agustina San Martín (To Kill the Beast) is set to direct, and casting is now underway.

Set in 19th-century New Mexico, Wolf at the Door follows a young woman on the eve of giving birth to her first child who foresees the return of a deadly half-man, half-wolf creature, only to discover that another predator already shares the hacienda she calls home. Treviño Orta’s play is part of a trilogy inspired by Latinx mythology and the Brothers Grimm fairy tales, and she adapts it for the screen herself.

San Martín is already deep in genre territory. She directs the upcoming psychological horror film Psyche, starring Noah Jupe (A Quiet Place) and Isabela Merced (The Last of Us), which is currently in post-production. Her debut feature, To Kill the Beast, premiered in the Discovery section at TIFF in 2021, and her short Monster God earned a Special Mention from the jury at Cannes.

Treviño Orta is an award-winning playwright whose works include Braided Sorrow and The River Bride, and whose ongoing cycle of fairy tales draws on Latin American folklore. The film is produced by Sophia Dilley (Stax: Soulsville, USA) and Charles Hopkins (Billy Preston: That’s the Way God Planned It).

“The original story and mythology of Marisela’s stage play serves as the perfect blueprint for an elevated horror feature film, and Agustina’s visual and atmospheric filmmaking sensibility makes her the perfect director to bring this stage story to cinemas,” said Charles Hopkins, producer, Concord Originals.

Concord Originals, which acquired the legendary RKO studio library in 2025, has not yet announced a production start or release date for Wolf at the Door.
