Kieran Culkin made his movie debut at 7 playing Fuller, the rubber sheet-requiring little cousin of Macaulay Culkin's Kevin McCallister in the 1990 blockbuster that made the elder Culkin brother a full-fledged star and put Kieran on the map.
"I didn't even know what the movie was about when we were doing it," Kieran said on the Late Late Show With James Corden in 2020. "There's a part in the movie where there's a kid who gets his head counted incorrectly and he goes, 'Bye, bring me back something French!' I thought the movie was about that kid."
Kieran teamed up again with Macaulay in this 1991 John Candy comedy, this time the two playing brothers in director Chris Columbus' follow-up to Home Alone.
Brother-of-the-bride Matty Banks helpfully pointed out that no one wants to see the word "pit" on a wedding invitation in the 1991 classic. Kieran returned for the 1995 sequel and the mid-pandemic 2020 virtual reunion.
In 1993, a single mother of two in distress couldn't do much better than having Jean-Claude Van Damme as her savior, as he was in one of the countless solitary-beefcake-saves-woman-from-human-or-machine-villain movies that were so popular at the time. Rosanna Arquette played a widow whose farm was under threat from ruthless contractors, Kieran was her son and the Muscles From Brussels was the escaped convict who makes everything right.
So...there was a sequel to A Christmas Story and this 1994 family comedy was it, also directed by Bob Clark and based on Jean Shepherd's stories but starring Kieran as Ralphie Parker and Charles Grodin and Mary Steenburgen as his parents. Once again, there's a bully to be vanquished, but without the snow.
Youngest Culkin sibling Christian also joined the family as Ralphie's little brother Randy, and it's his sole acting credit.
Sharon Stone played Kieran's mom in this heartwarming tearjerker about two misfit kids whose friendship gives them the inner superpowers they need to get by in their small town.
Kieran played younger brother Simon to Rachael Leigh Cook's social outcast-turned-potential-prom-queen Laney Boggs in the 1999 teen classic.
Also in 1999, Kieran joined Tobey Maguire as resident "Princes of Maine" and "Kings of New England" in the orphanage-set drama that resulted in Oscar wins for John Irving's screenplay and supporting actor Michael Caine.
In 2002 Kieran earned his first Golden Globe nomination for acting in a comedy for his turn as the titular New York rich kid dealing with an institutionalized father (Bill Pullman), an alcoholic mother (Susan Sarandon), an Alex P. Keaton-type brother (Ryan Phillippe), a mad crush on a girl (Claire Danes) and an affair with a woman (Amanda Peet) who's already the trophy mistress of his real estate tycoon godfather (Jeff Goldblum).
It's a hoot, albeit a dark one.
The Catholic school travails of four friends growing up in Savannah, Ga., in the 1970s drive the coming-of-age action of this 2002 dramedy based on Chris Fuhrman's inspired-by-his-real-life novel of the same name.
Martin Scorsese executive-produced this 2008 drama-with-humor starring Rory Culkin as Scott, a sweet 15-year-old in 1979-era Long Island who's in love with his neighbor Adrianna, played by Emma Roberts. Life gets complicated when Adrianna's dad (Timothy Hutton) is diagnosed with Lyme disease and her mother (Cynthia Nixon) starts having an affair with Scott's father (Alec Baldwin). Meanwhile, his older brother Jimmy (Kieran), already no fan of their dad, is over all the parental hypocrisy.
Kieran plays one of the few people Michael Cera doesn't have to battle in the 2010 cult-classic based on a graphic novel series. But upon closer inspection, Scott's roommate Wallace Wells is giving strong doesn't-give-AF-but-still-endearing Roman Roy vibes, only with much less profanity.
Kieran plays Paul, a slacker schoolmate of the interminably self-centered Margaret (Anna Paquin) who decides Paul's the guy she should lose her virginity to while also obsessively trying to atone for a bus accident she helped cause.
The real news, however, is that J. Smith-Cameron—Gerri, the object of Roman's twisted affection on Succession—played Margaret's mom in the very long film directed by Cameron's husband, Kenneth Lonergan.
He isn't around for long, but Kieran had a memorable turn on the second season of Fargo as Rye Gerhardt, a junior member of a murderous crime family, whose hit-and-run death in the season premiere triggers much of the ensuing action. (Though, more accurately, Rye is hit and Kirsten Dunst's Peggy Blumquist calmly drives home with him still embedded in her windshield.)
Kieran's gangsters don't have much luck. It's kill or be killed on the job in this Steven Soderbergh-directed all-star crime saga from 2021, and his character is, well...
Kieran has won two Critics' Choice Awards and been nominated for two Emmys and three Golden Globes for his pitch-perfect turn as the remarkably crass and calculating but obviously-in-need-of-a-hug Roman Roy, the youngest of Logan Roy's 3D-chess-playing heirs.
