Rory Culkin Bio: Age, Height, Girlfriend, Career, Nocturne 2026, Net Worth & Facts

Rory Culkin spent most of his childhood as “the youngest Culkin,” the baby in the family photo and the kid brother in his siblings’ movies. In 2026 he became something else: the quiet scene-stealer of Apple TV’s Nocturne, holding his own opposite Stephen Graham in one of the year’s most unsettling psychological thrillers.

As Karl Anders, a gentle nurse assigned to watch a notorious serial killer, Culkin plays the one person who refuses to see a monster as only a monster. The performance has reminded critics that he has been doing serious work for 25 years, since he was 11 years old in You Can Count on Me.

This biography covers Rory Culkin’s age, height, family, girlfriend and child, his upbringing in the Culkin acting dynasty, his career from Richie Rich to Nocturne, his awards, net worth and the controversies that come with being a Culkin.

Quick Facts

People who search for Rory Culkin often also look up Macaulay Culkin, Kieran Culkin, Bonnie Bedelia, Stephen Graham, Nocturne, Scream 4 and Succession, because his family name connects him to almost every corner of modern American acting.

Early Life & Education

Rory Hugh Culkin was born on July 21, 1989, in New York City, the youngest of seven children. His father, Christopher “Kit” Culkin, was a former Broadway stage actor; his mother, Patricia Brentrup, was a North Dakota native who met Kit in 1974 while working as a road traffic controller in Sundance, Wyoming.

His siblings are Shane, Dakota, Macaulay, Kieran, Quinn and Christian. His paternal aunt is actress Bonnie Bedelia, best known for Die Hard and Presumed Innocent. The family lived in a cramped apartment on Manhattan’s Upper East Side, and by the early 1990s the household income depended almost entirely on the children’s acting work.

Rory has German, Irish and Norwegian ancestry. His formal education is not publicly documented, and he has said little about school. What is clear is that he grew up on film sets: he was carried on as a baby, photographed as an infant in The Good Son (1993) and cast as Young Richie in Richie Rich (1994) alongside his brother Macaulay.

Career Journey

Culkin’s career can be divided into five phases: the family-era child roles, the breakthrough as a serious young actor, the indie years, the television reinvention and the Nocturne moment.

A Baby Photo and a Family Business (1993–1999)

His first appearance was literally a photograph: baby Rory in The Good Son (1993). A year later he played Young Richie in Richie Rich, the story of the world’s richest boy, with Macaulay in the lead.

He continued to work as a younger version of his brothers’ characters, including 10-year-old Igby in Igby Goes Down (2002), where Kieran played the older Igby. It was steady work, but it also meant that for years his identity on screen was defined by whoever else was in the frame.

You Can Count on Me and Child Stardom (2000–2005)

Culkin’s breakthrough came in 2000, when he played Rudy Prescott opposite Laura Linney and Mark Ruffalo in You Can Count on Me. The role earned him a Young Artist Award and, more importantly, critical respect that had nothing to do with his surname.

He followed it with Signs (2002), M. Night Shyamalan’s alien-invasion thriller, playing Morgan Hess, the asthmatic son of Mel Gibson’s character. The film was a massive box office hit and made him recognizable to a global audience.

In 2004 he starred in Mean Creek, a dark indie drama about teenagers who plot revenge on a bully. The film won the Robert Altman Award for ensemble acting at the Independent Spirit Awards, and it marked his transition from child actor to young adult performer.

Mean Creek, Scream 4 and Indie Cred (2004–2016)

The years after Mean Creek were spent almost entirely in independent film. He appeared in The Zodiac, The Chumscrubber, Down in the Valley, The Night Listener, Lymelife, Twelve and Hick.

In 2011 he played Charlie Walker in Scream 4, a role that introduced him to a new generation of horror fans and gave him one of the film’s most memorable death scenes.

He continued with Electrick Children (2012), Gabriel (2014), Jack Goes Home (2016) and Columbus (2017), the last of which became one of the best-reviewed indies of his career.

Television and Character Work (2017–2023)

Culkin’s television work changed the trajectory of his career. He played David Thibodeau in Waco (2018), Willie in Castle Rock (2018), Clay Roach in City on a Hill (2019) and Tyler in The Expecting (2020).

In 2018 he played Euronymous, the Norwegian black metal musician, in Lords of Chaos, a role that required him to learn guitar parts and adopt a scene and a philosophy far from his own. In 2021 he played designer Joel Schumacher in Halston, and in 2022 he appeared as Samuel Lafferty in Under the Banner of Heaven.

In 2023 he appeared in Swarm and in the Black Mirror episode “Beyond the Sea,” playing Kappa opposite Aaron Paul and Josh Hartnett. The episode’s bleak premise and his quiet performance were widely discussed online.

Nocturne and a New Leading Role (2024–Present)

In 2024 he appeared in 5lbs of Pressure and Dead Money. In 2025 his short film Dear Shop Girl premiered at the Woodstock Film Festival, and he began promoting Nocturne, Apple TV’s psychological crime thriller about a nurse and the serial killer he is assigned to monitor.

The series premiered in late October 2026 with Stephen Graham as Jurek Walter, a manipulative killer held in a restricted housing unit, and Culkin as Karl Anders, the nurse who keeps breaking the rules to help him. Reviews singled out the chemistry between the two actors, and the show became one of the fall’s most talked-about releases.

Career Stats

Personal Life

Culkin is private to the point of being reclusive. He does not run a public social media account, rarely gives interviews and almost never discusses his family in detail, which is understandable given how much of his childhood was spent in public.

He has been in a relationship with Katelin Arizmendi since 2023, and the couple has one child. He has not shared the child’s name or birth details publicly.

He lives in New York, where he grew up, and has said that staying close to his family and away from Los Angeles is deliberate. His siblings include some of the most famous actors of their generation, and he has described the Culkin name as both a door opener and a burden.

Dating History and Affairs

Rory Culkin’s romantic life has been almost entirely out of the press. There is no confirmed dating history beyond his current relationship, and no tabloid record of affairs or public breakups.

He has been with Katelin Arizmendi since 2023. The two have appeared together at events but have not discussed their relationship in interviews, and they have not shared their child’s name publicly.

For someone whose family was tabloid fodder for years, that is a deliberate choice rather than an accident.

Controversies

Culkin has avoided personal scandal, but his career and family have produced plenty of friction.

• The Culkin family rift. His father, Kit Culkin, fought a bitter legal and public battle with Macaulay’s representatives in the 1990s over control of his son’s earnings. Rory was a child during the worst of it and has rarely spoken about it.
• Nepotism perception. He has been accused, mostly implicitly, of benefiting from his surname. His response has been to work steadily in independent film and television rather than chase blockbusters.
• Lords of Chaos backlash. The 2018 film dramatized real murders and church burnings in the Norwegian black metal scene, and it drew criticism from people close to the victims and from musicians who said it exploited a tragedy.
• Black Mirror intensity. “Beyond the Sea” is one of the series’ most disturbing episodes, and some viewers criticized its violence. Culkin’s performance was praised even by viewers who disliked the episode.
• Privacy and the press. His refusal to engage with celebrity media has occasionally been reported as aloofness, particularly when he declines to discuss his brothers.

Awards & Achievements

Culkin’s awards shelf is small but meaningful, and it reflects a career built on ensemble work rather than starring vehicles.

• Young Artist Award for his performance in You Can Count on Me (2000).
• Robert Altman Award (ensemble) at the Independent Spirit Awards for Mean Creek (2005).
• Gotham Award recognition for his leading role in Gabriel (2014).
• Critical acclaim for Columbus (2017), one of the best-reviewed films of the year.
• A career-reviving turn in Nocturne (2026) opposite Stephen Graham.
• A 25-year filmography that includes more than 40 features and television roles.

He has never been nominated for an Oscar, Emmy or Golden Globe, and he has said he is not chasing them.

Physical Statistics

Culkin is widely listed at around 5 feet 8 inches. He has a lean build, brown hair and brown eyes, and he tends to look younger than his age, which helped him play younger brothers for years and now helps him play gentle, unworldly characters like Karl.

Quotes

Culkin gave one of his most revealing interviews of the year to Decider in November 2026, explaining how he built the relationship between Karl and Jurek.

“I approached it like I’m tasked with an exotic predator. He’s beautiful and scary, but fascinating. But if he were to get his paws on me, he would tear me apart, and that just makes him even more fascinating.”

Rory Culkin, Decider, November 6, 2026

“We’re playing this all through a window, and it’s like being in a zoo, and the tiger’s looking right at you. It’s exciting, it’s exhilarating, and it’s making Karl feel things that he’s never felt, or he hasn’t felt in a very long time.”

Rory Culkin, Decider, November 6, 2026

“I think with Karl, there’s good in everyone, even the worst of us.”

Culkin does not share much about his personal tastes, so this list stays with what he has said on the record.

Earnings

Rory Culkin’s net worth is estimated at around $3 million, a figure that reflects a long career of independent films, television roles and the occasional studio project rather than a single blockbuster payday.

His biggest commercial hits were Signs and Scream 4, but child actors typically earn far less than the stars around them, and indie films pay scale rather than gross points. His television work, including Waco, Under the Banner of Heaven and Nocturne, has been steadier and better paid.

He does not endorse products, does not run a media company and has no public business ventures. The estimate is a calculation based on reported fees, not a disclosed figure.

Conclusion

Rory Culkin has spent his whole life in the shadow of a famous family and has quietly built a career that stands on its own. From a baby photo in The Good Son to the nurse at the center of Nocturne, he has chosen difficult, small-scale roles over easy celebrity.

His performance as Karl Anders may be the one that finally changes how the industry sees him: not as the youngest Culkin, but as an actor who can carry a scene with Stephen Graham and make an audience sympathize with someone who should know better.
