A24 has acquired the North American rights to “Saint Maud,” a psychological horror film that made its world premiere in TIFF’s Midnight Madness program, an individual with knowledge of the deal told TheWrap.

“Saint Maud” is the first feature film from British writer-director Rose Glass, whose previous work includes the short “Room 55.” It next makes its U.S. premiere at Fantastic Fest on Sept. 19. No release date has yet been set. It will also be playing next month in competition at the BFI London Film Festival.

“Saint Maud” follows a pious but unstable nurse, Maud, who becomes convinced that she must save the soul of her dying employer, Amanda, as signs of eternal damnation begin to present themselves in their isolated seaside town. The film nods to other religious horror films, most notably “The Exorcist,” among others.

Oliver Kassman and Andrea Cornwell produced “Saint Maud,” and the film is executive produced by Daniel Battsek, Sam Lavender, and Mary Burke.

The film was developed by Film4, and production was backed by Film4 and the BFI (using National Lottery funds), and produced by Escape Plan Productions. Protagonist Pictures is handling worldwide sales. Sony Pictures Worldwide Acquisitions holds all international rights to the film, excluding the U.K. and France.

Glass is represented by Tracey Hyde at Casarotto Ramsay.
