Apple TV’s psychological crime thriller Nocturne is earning widespread acclaim as one of the most intense and compelling television dramas of the year, with viewers and critics singling out Stephen Graham’s performance as a career-defining turn in terrifying screen villains.
Adapted from the bestselling novel The Sandman by Lars Kepler (the pen name of writing duo Alexander and Alexandra Coelho Ahndoril), the series pairs Graham with Liev Schreiber and Zazie Beetz in a high-stakes investigation that blurs the lines between detective procedural and psychological cat-and-mouse suspense.
