M. Night Shyamalan announced last week he officially started filming his 15th movie, the mysteriously named Knock at the Cabin, and production will take place in and around Philadelphia and in South Jersey.

Shyamalan last week posted a photo announcing that production on the film had officially commenced, holding a clipperboard with the film’s title and an image of foggy, spooky woods. Parts of the movie will be filmed in Philadelphia, around the city and in Burlington County.

Shyamalan, who was raised in Lower Merion, often films his movies in Philadelphia and its suburbs, a tribute to his childhood.

Little is known about the film, though if it’s anything like Shyamalan’s previous work, it will be a simmering, creepy thriller, complete with his now-trademark mind-blowing twists.

The two leads of the film are Ben Aldridge, who starred in Pennyworth, a TV series based on the Batman comics, and Lancaster native Jonathan Groff, who starred in the Netflix series Mindhunters. Also announced for the cast are Dave Bautista, Rupert Grint — who currently stars in Servant, where Shyamalan serves as showrunner and executive producer — and Nikki Amuka-Bird, who starred in Shyamalan’s last film Old.

Shyamalan will write, direct, and produce the film for Universal Pictures. The film is scheduled to premiere February 3, 2023.
