Abigail’s growing attachment and Patrick’s doubts create the central uncertainty in Mark Heyman’s film.
Patrick and Abigail do not experience the retreat’s leader in the same way. Vertical’s description of Pendulum places Abigail increasingly under that person’s influence while Patrick becomes more fearful about what is happening. Vertical’s official character premise.
The conflict gives Patrick two things to investigate at once: the group his wife is joining and his own interpretation of it. The distributor frames his uncertainty as part of the story, without settling whether the retreat is a cult or whether his perceptions can be trusted.
Joseph Gordon-Levitt plays Patrick and Phoebe Dynevor plays Abigail. The film is written and directed by Mark Heyman. Entract Films’ cast listing also includes Jacki Weaver and Norman Reedus. Vertical’s official character premise. Entract Films’ credits and Canadian release details.
Entract lists January 1, 2027, as its Canadian release date. The premise keeps the couple’s disagreement at the center of the horror: participation brings one person closer to the leader while making the other increasingly suspicious. Entract Films’ credits and Canadian release details.
