Carla Gugino (The Adventures of Cliff Booth) and Lou Taylor Pucci (Touch Me, You) are set to star in Winthrop, a new horror movie based on the cult podcast Knifepoint Horror.

Winthrop will the episode “The Lockbox” by writer, creator, and narrator Soren Narnia.

Gugino will star as a woman “who puts her life on the line to protect her troubled, enigmatic cousin, Winthrop (Pucci), who has been targeted and hunted by a powerful supernatural force.”

Daniel Stamm (The Last Exorcism, Prey for the Devil) is set to direct from a script by Emmy-winning playwright Justin Yoffe. Production is set to begin this summer in Canada.

In a statement on the project, producer Kearie Peak said, “Winthrop captures the eerie dread that makes ‘Knifepoint Horror’ such a success. Carla Gugino is a perfect fit for the film, bringing a rare intensity and subtlety that aligns perfectly with the silent horror of Winthrop. Beneath the supernatural tension, the film explores how generational trauma festers and twists over time. It’s horror with weight, and it stays with you.”

AURA Entertainment will handle Winthrop‘s U.S. theatrical release, with MGM+ handling its streaming and linear debut.

Deadline first reported on Winthrop.
