Horror fans got an early Halloween treat this week. Norman Reedus shared the new trailer for Pendulum on Instagram on October 30, just one day before the 16th anniversary of The Walking Dead, the series that made him a household name. The timing was no accident, and the footage itself is about as far from a celebratory throwback as it gets: a slow, creeping descent into a desert retreat where healing curdles into something far darker.
Pendulum opens in theaters nationwide on January 1, 2027, giving horror lovers a suitably unsettling way to ring in the new year. Distributed by Vertical, the R-rated film runs 109 minutes and stars Joseph Gordon-Levitt, Phoebe Dynevor, Jacki Weaver, Anna Deavere Smith, Jena Malone and Reedus.
What Pendulum is about
At the centre of the film are Patrick, played by Gordon-Levitt, and Abigail, played by Dynevor, a married couple travelling to a secluded new-age retreat in New Mexico after a traumatic event. They arrive drawn by the possibility of healing. What they find instead is a community built around an enigmatic leader, played by Weaver, whose spiritual practices promise transformation but demand total surrender.
According to the official synopsis, Patrick is willing to do anything to help his wife, but he grows distrustful of the retreat’s leader even as Abigail falls under her spell. As paranoia builds, the couple must work out whether the group’s rituals offer genuine healing or mask a terrifying truth that threatens to consume them both.
The trailer leans hard into that split. It opens in a hushed, grief-shadowed home before cutting to the sun-bleached isolation of the New Mexico retreat. From there, the imagery turns stranger and more ritualistic: chanting, trance-like gatherings and the creeping suggestion that death itself may not be the end. That promise lands as a threat rather than a comfort.
The Black Swan connection behind the camera
Pendulum marks the feature directorial debut of Mark Heyman, who co-wrote Darren Aronofsky’s Black Swan. Aronofsky produces through his Protozoa Pictures banner, alongside Jacob Jaffke and Dave Caplan, whose credits include Longlegs. Heyman has described the film as growing out of his upbringing in and around spiritual groups and gurus his parents explored in the 1970s and 1980s, and has said much of it is inspired by one of their stranger encounters.
That personal root shows in the trailer’s central question. Heyman has said he wanted to capture how people get drawn into cult-like groups and the danger of surrendering yourself completely to the unknown. Where Black Swan charted a dancer’s psychological unravelling, Pendulum appears to chart a marriage unravelling under the pressure of grief, belief and manipulation.
For Reedus, the film is a return to the genre that defined his career, albeit in a very different register from Daryl Dixon. His role in Pendulum has not been publicly disclosed, which only adds to the intrigue for fans of The Walking Dead universe. The original series premiered on AMC on October 31, 2010, with the pilot episode “Days Gone Bye,” and ran for eleven seasons.
Why the January 1 release date matters
A New Year’s Day theatrical release is a statement of confidence. January has become a reliable corridor for horror, and a wide release on the first day of the year puts Pendulum in front of viewers before the 2027 slate gets crowded. The R rating, for some strong and bloody violent content, sexuality, drug use, nudity and language, signals that the film is not softening its premise for a broader audience.
The casting, too, is a draw in its own right. Gordon-Levitt anchors the film’s emotional core as a husband watching his wife slip away into a belief system he cannot trust, while Dynevor takes on a far darker register as Abigail. Weaver, an actor who can make warmth feel menacing, is ideally cast as a leader whose serenity may be a mask.
What to watch for next
With two months to go until release, expect a final trailer and early critical reaction as the film heads toward its January bow. The questions that will shape its reception are already clear: how far does Heyman take the supernatural element, and does the marriage at its centre survive the retreat’s pull? For now, the trailer has done its job, turning a quiet Instagram share from Reedus into one of the most talked-about horror previews of the week.
If the full film delivers on the trailer’s atmosphere, Pendulum could be the first horror talking point of 2027, and a reminder that the most frightening monsters are sometimes the ones offering to heal you.
