AURA Entertainment will handle the U.S. theatrical release, with MGM+ handling the streaming and linear debut.
Previously known as Winthrop.
Filmed in Vancouver in 2025.
One of the film's producers was quoted saying: "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."
Directed by Daniel Stamm (The Last Exorcism, Prey For the Devil).
Based on "The Lockbox" episode from the Knifepoint Horror podcast by creator and narrator Soren Narnia.
