Nocturne Review: Stephen Graham Is TV's Most Evil Serial Killer 2026

Stephen Graham delivers a chilling performance as serial killer Jurek Walter in the new 10-part psychological thriller Nocturne, a show that is as mesmerizing as it is disturbing. The series, which airs on television and streaming, has already sparked intense debate about whether Graham has overtaken Anthony Hopkins as the screen's most unsettling serial killer.

Walter is incarcerated for life in the bowels of Riverside psychiatric hospital in Pittsburgh, Pennsylvania. He passes the time by doing push-ups, stashing contraband behind his toilet bowl, and driving fellow inmates to suicide by whispering to them through the pipes. Graham – muscle-bound, preternaturally still and occasionally emitting a high-pitched giggle – is utterly terrifying.

The Performance That Redefines Evil

Graham's portrayal of Walter is a masterclass in understated menace. He doesn't rely on grand gestures or explosive outbursts; instead, he uses stillness and a soft, almost gentle voice to manipulate those around him. As one former nurse notes, Walter has a way of making you feel sorry for him – "a man who buried people alive."

This ability to elicit sympathy is what makes Walter so dangerous. He draws out the deaths of his victims in order to torture their families as much as the individuals themselves. Graham captures this sadism with a quiet intensity that is far more frightening than any overt violence.

From Hannibal to Jurek Walter

Anthony Hopkins's Hannibal Lecter set the benchmark for sophisticated screen villains. But Graham's Walter is a different breed: less cultured, more primal, yet equally calculating. The torch may finally have passed.

The Plot: A Young Nurse's Downfall

Walter soon has his hooks into his new nurse, Karl (Rory Culkin), who is too young, inexperienced and tender-hearted to heed the staff's warnings about the manipulative monster in the basement. Karl becomes a pawn in Walter's game, offering up personal information and carrying illicit messages to his supposed lawyer.

The series explores how easily good intentions can be exploited. Karl's empathy, which should be a strength, becomes his vulnerability. It's a cautionary tale about the dangers of engaging with evil on its own terms.

Why Nocturne Is Impossible to Stop Watching

Despite its dark subject matter, Nocturne is compulsively watchable. The pacing is deliberate, building tension slowly rather than relying on jump scares. The writing is sharp, and the supporting cast – including Rory Culkin – delivers nuanced performances.

The show also raises questions about the nature of evil and the limits of rehabilitation. Walter is not a monster in the supernatural sense; he is a human being capable of horrific acts. That makes him all the more terrifying.

• Stephen Graham's performance is a career-best, blending stillness with sudden, unsettling bursts of energy.
• The psychological manipulation is the show's core, making it a tense, character-driven thriller.
• Rory Culkin's Karl provides the audience's entry point, his vulnerability making the danger feel real.
• The setting – a psychiatric hospital's basement – adds claustrophobia and a sense of inescapable dread.
• The writing avoids clichés, focusing on the slow burn of psychological horror.

How Nocturne Compares to Other Serial Killer Dramas

Serial killer dramas are a crowded field, but Nocturne stands out for its restraint. It doesn't glorify violence; instead, it examines the aftermath and the psychological toll on those who come into contact with Walter. Context on how this played out before sits in Nocturne Review: Stephen Graham Is TV's Most Evil Serial Killer.

While Hannibal Lecter is known for his refined tastes, Walter is a more visceral threat. He doesn't need a fancy dinner party to get under your skin; a whispered conversation through a pipe is enough. The background to this story is set out in Celebrity: latest articles.

The Cultural Impact of Stephen Graham

Stephen Graham has long been one of Britain's most reliable actors, but Nocturne may be the role that defines his career. His transformation into Walter is complete, from the physicality to the voice. It's the kind of performance that lingers long after the credits roll. Earlier coverage in Stephen Kovacevich: Pianist Who Risked Oblivion for Art shows how the argument developed. A closer look at the same subject appears in Save Radio 4 Extra: Why BBC Cuts Threaten Cultural Heritage.

The show has already generated buzz online, with viewers praising Graham's chilling portrayal. It's a reminder that the most frightening villains are often the ones who seem most human.
