Apple TV has announced the release of Nocturne, a new event series set to debut on October 30, 2026, during the Halloween period. The series is adapted from the novel The Sandman, written by Lars Kepler in 2012. Created by Rowan Joffé and John Hlavin, Nocturne follows Jonah Lynn, a former soldier turned detective in the criminal division who has settled in a small town in Pennsylvania to lead a quiet life. However, he will face Jurek Walter, a diabolical serial killer threatening his family's safety. The first trailer for Nocturne has been released, showcasing a cast including Liev Schreiber as Jonah Lynn, Zazie Beetz as Saga Bauer, and Stephen Graham as Jurek Walter. Additional cast members include Bill Camp, Rory Culkin, Chrissy Metz, Poorna Jagannathan, and Gary Carr. The trailer highlights tense scenes of investigation, suspense, and personal conflict, suggesting a psychological thriller with elements of horror and drama. The series will consist of 10 episodes, with the first two episodes released simultaneously on October 30. Subsequent episodes will be released weekly every Friday, with the full story available to Apple TV subscribers by December 25, 2026. This release strategy is designed to build anticipation and maintain viewer engagement over several months. Nocturne is expected to draw comparisons to other crime and thriller series due to its intense narrative and strong performances. With a focus on character development and a gripping storyline, the show aims to captivate audiences during the Halloween season and beyond. Fans of the original novel may find both familiar and new elements in this adaptation, as the creators have taken liberties to translate the story into a visual format.
