Monster: The John Wayne Gacy Story is an American crime drama television miniseries created by Jane Holloway for HBO. Initially announced under the working title Dark Pursuit, the project was later folded into the Monster anthology banner. Directed by Lena Ortega, the eight-episode series dramatizes the life and crimes of serial killer John Wayne Gacy and the institutional failures that allowed his offenses to persist. In April 2026, HBO announced a follow-up season in the anthology, Monster: The Bernie Madoff Story, slated to begin production in late 2026 for a planned fall 2027 release.

The series stars Michael Shannon as Gacy, with Paul Dano, Kaitlyn Dever, Nick Offerman, and Jovan Adepo in principal roles. Supporting performers include Bill Camp, Jessie Buckley, Jeremy Allen White, Mary Elizabeth Winstead, and Scoot McNairy, with guest appearances by Patton Oswalt, Lili Taylor, and Lucas Hedges. The show premiered on February 8, 2026, and concluded on March 29, 2026, airing weekly on HBO and streaming on Max.

Blending psychological drama with procedural storytelling, the miniseries emphasizes restraint over graphic depiction, focusing on community complicity, survivors’ families, and the investigative work that led to Gacy’s arrest, trial, and execution. Critics praised its tension, direction, and performances—particularly Shannon’s portrayal—while some commentary noted ongoing debates about the ethics of dramatizing real-world tragedies.

1	"The Clown"	February 8, 2026 (2026-02-08)
In 1972, contractor and part-time entertainer John Wayne Gacy appears at a suburban Illinois street fair, dressed as "Pogo the Clown" while mingling with neighbors and local officials. His cheerful public demeanor contrasts with ominous scenes inside his home, where a locked basement door hints at hidden horrors. Gacy expands his reputation by volunteering at Democratic Party events and offering work through his contracting company, drawing in vulnerable young men such as Tim Kelly. When Tim vanishes after attending one of Gacy’s gatherings, police dismiss the family’s report as another runaway case. The narrative underscores institutional blind spots and missed warnings. In the closing sequence, Gacy silently removes his makeup at a bathroom mirror, his reflection vacant as muffled cries seep from beneath the floorboards.
2	"House of Secrets"	February 15, 2026 (2026-02-15)
Detectives canvass neighborhoods following Tim’s disappearance, with Harmon questioning Gacy directly. Gacy deflects suspicion by echoing authorities’ claims that the boy likely ran away. Meanwhile, Harding compiles cases of missing young men from surrounding towns, noticing striking similarities in the accounts of parents. Her editor warns her against “fearmongering,” but she persists. Rivers, an apprentice employed by Gacy, grows uneasy after hearing rattling from a locked crawl space during late-night work. The episode climaxes with a backyard barbecue where Gacy entertains guests while ominous shots linger beneath the house, water dripping and muffled sounds barely audible. Rivers stares at the crawl space door, his unease signaling that the danger is no longer hidden from those closest to him.
3	"Missing Boys"	February 22, 2026 (2026-02-22)
A montage shows families posting missing posters across town as police dismiss most cases as runaways. Wells becomes the emotional centerpiece, grieving her son’s disappearance and refusing to accept official explanations. Harmon begins linking missing persons cases, but Crampton argues resources cannot be spared. Harmon notes that many victims once worked for Gacy’s contracting business. Harding publishes her first article tying Gacy to the disappearances, sparking uproar in the community, where some defend him while others whisper doubts. Rivers confronts Gacy about crawl space noises, only to be mocked and gaslit. The episode ends at a candlelight vigil where grieving families gather; Gacy himself attends, shaking hands with parents as Harmon stares at a wall of missing boy photos, realizing the true scale of the case.
4	"The Double Life"	March 1, 2026 (2026-03-01)
Gacy attends a local political fundraiser where Rayner praises him as a model citizen, but intercut sequences show his private life unraveling. For the first time, the narrative depicts Gacy luring young men into his home under the pretense of work or parties, employing the “handcuff trick” in a chilling scene that shifts from playful to violent. Rivers, increasingly fearful, hears cries echoing from beneath the floorboards while cleaning tools in the garage. When he confronts Gacy, he is dismissed with mocking laughter. The second half enters the crawl space itself, revealing narrow tunnels, dirt walls, and hidden bodies. The episode ends with Gacy entertaining children at a birthday party, painting a balloon with a grotesque smile as the camera cuts between laughing guests above and the grim reality below.
5	"Buried Beneath"	March 8, 2026 (2026-03-08)
Harmon grows increasingly obsessed as he studies a map of missing boys, confronting Crampton over inaction and pushing for surveillance on Gacy. Harding publishes a follow-up article that directly names Gacy as a link in the disappearances, inciting outrage at town hall meetings. In the shadows, Gacy deflects criticism by portraying himself as a persecuted neighbor. Rivers, overwhelmed by paranoia, sneaks back into the house and discovers disturbed soil in the crawl space, fleeing in horror before uncovering more. Later, Harmon tails Gacy to a remote field where he observes him digging at night in eerie silence. The episode ends with Gacy waving from a Christmas parade in clown costume, unaware that police are quietly preparing warrants as the community still sees him as a smiling friend.
6	"The Search Tightens"	March 15, 2026 (2026-03-15)
Harmon pushes once again for surveillance, and Crampton reluctantly approves after another teenager vanishes. Investigators interview former employees, gathering chilling accounts of Gacy’s “tricks” and inappropriate offers, though none enough to secure a warrant. Harding’s articles fuel public outrage but also spark threats from Gacy’s defenders. Surveillance begins, capturing late-night drives and a tense moment when Gacy notices he is being tailed, locking eyes with an undercover detective at a gas station. Meanwhile, Rivers sneaks into the crawl space and uncovers partially buried remains, fleeing in terror. Gacy unravels publicly, drinking heavily and faltering during clown performances, his facade cracking. The episode ends as Harmon finally secures a warrant, officers preparing outside Gacy’s home at night while he stares calmly from a window, smiling faintly as if anticipating the inevitable.
7	"Confessions"	March 22, 2026 (2026-03-22)
Officers execute the warrant at Gacy’s home, beginning a cautious search that uncovers photographs, implements, and the stench of decay. In the basement, flashlights sweep the crawl space, exposing disturbed soil and fabric scraps. Harmon brings Gacy into questioning; the suspect jokes and deflects until missing-persons files and timelines pile up, each tying him closer to the disappearances. Outside, neighbors watch in disbelief as the yard becomes a crime scene and families gather for news. Under pressure, Rivers gives a detailed account of what he heard and saw beneath the house, his testimony aligning with new physical evidence. The interrogation turns as denials collapse; Gacy begins to admit to murders in a chilling, matter-of-fact cadence, describing lures, the handcuff trick, and burials below. As confessions continue, officers recover multiple remains from the crawl space. The episode closes with Harmon stepping into the cold night amid reporters, while Gacy sits alone in a cell, faintly smiling in the dark.
8	"The Crawl Space"	March 29, 2026 (2026-03-29)
In the aftermath of the confessions, police flood the property as the crawl space is excavated under floodlights, news cameras broadcasting the discoveries nationwide. Families clutch photographs outside, demanding justice. In court, prosecutors build a meticulous case with forensic evidence, timelines, and testimony from Rivers, Wells, and Harmon; the defense argues instability, but the scale of the crimes overwhelms the room. Gacy shows no remorse, twisting prior admissions into boasts of control. The narrative spans years on death row—letters, paintings, interviews—contrasted with families rebuilding in the shadow of loss. The finale depicts his 1994 execution with stark restraint, focusing on witnesses rather than spectacle. A closing montage returns to the neighborhood decades later, children playing in the street, before the camera settles on the sealed crawl space—an empty chamber where the truth once hid.

Production

The project was first announced by HBO in September 2025 under the title Dark Pursuit. Jane Holloway was set as creator and writer, with Lena Ortega attached to direct all episodes.

Later that month, the project was retitled Monster: The John Wayne Gacey Story to align with the Monster brand of dramatized true-crime anthology series.

In September 2025, HBO confirmed an eight-episode order, episode titles, and release schedule.

Casting was officially unveiled on February 2, 2026, with Michael Shannon in the lead role alongside Paul Dano, Kaitlyn Dever, Nick Offerman, and Jovan Adepo. The ensemble includes Bill Camp, Jessie Buckley, Jeremy Allen White, Mary Elizabeth Winstead, and Scoot McNairy, with guest roles for Patton Oswalt, Lili Taylor, and Lucas Hedges.

Filming began in early 2025 in Chicago, with a reported budget of $85 million.

Reception

Critical response

Monster: The John Wayne Gacey Story received strong critical acclaim across its eight-episode run, with reviewers consistently praising its atmosphere, performances, and refusal to sensationalize its subject matter.

The premiere, "The Clown," was highlighted for its restrained tension and unsettling authenticity, establishing the series’ psychological approach to Gacy’s double life. "House of Secrets" was praised for its suffocating dread, with critics noting Michael Shannon’s chilling performance and Jovan Adepo’s growing unease as Anthony Rivers, even as the slower pacing deepened the suspense.

"Missing Boys" shifted the focus to families of victims, earning acclaim for Jessie Buckley’s raw portrayal of Martha Wells and for the vigil sequence that underscored the community’s mounting unease. The midpoint episode, "The Double Life," was described as “brutal but unforgettable,” with critics singling out Shannon’s performance and the claustrophobic depiction of the crawl space.

Later installments were noted for their procedural focus. "Buried Beneath" was praised for its investigative momentum and for Paul Dano’s increasingly obsessive portrayal of Harmon, with the Christmas parade finale cited as one of the season’s most haunting juxtapositions. "The Search Tightens" drew acclaim for its meticulous procedural detail, with critics pointing to the gas station surveillance sequence as a standout moment.

The penultimate episode, "Confessions," was widely considered the series’ most overwhelming hour. Reviewers praised its feature-length runtime, its intercutting of confessions with excavation scenes, and Adepo’s pivotal testimony, calling the result “devastatingly effective.”

The finale, "The Crawl Space," was described as a devastating and exhaustive conclusion. Critics highlighted its courtroom structure, restrained portrayal of Gacy’s execution, and focus on the families’ enduring grief, with one review calling it “a reckoning rather than a spectacle.”

Future

On April 10, 2026, HBO confirmed that the Monster anthology would return with a second season titled Monster: The Bernie Madoff Story. The season will pivot to white-collar crime, dramatizing Madoff’s rise as a Wall Street pioneer, the web of investors ensnared by his Ponzi scheme, the 2008 financial crisis that exposed the fraud, and the fallout—including lawsuits, ruined savings, and years of litigation. The series is expected to examine systemic oversight failures, blind trust in charisma, and the human toll of financial betrayal. Production is slated to begin in late 2026, with a tentative release window in fall 2027. Casting announcements are expected later in 2026.
