Yvonne Strahovski, Scott Speedman, Chaske Spencer, Kathy Baker, Boris McGiver, Caleb Dolden, Emilie Bierre and Luciano Leroux star in the series, which was ordered by Peacock in December 2022.
"When I read these scripts, I knew it was going to be a very character-driven slow burn," Speedman previously told reporters at Comic-Con. "It takes a while to get going, but when it does, it starts to make more sense and the horror elements come in."
