The 1990 comedy classic is funny, action-packed and heartwarming, topping 'best Christmas movie' consistently since its release.
Main character Kevin McCallister - a precocious eight-year-old boy who gets accidentally left at home alone over Christmas and is tasked with protecting his home from a duo of robbers - is undoubtedly a highlight.
Writer and producer John Hughes suggested 10-year-old Macaulay Culkin for the lead role having worked with him in Uncle Buck, but director Chris Columbus met with up to 200 child actors before finally meeting with Culkin and agreeing he was perfect for the part.
In the film, Kevin McCallister has four siblings and a massive nine cousins - part of the reason he was forgotten in the morning rush after the McCallisters overslept their alarm on the morning of their flight to Paris.
Most of us know what became of Macaulay Culkin - still the most famous of the brood - but what of the rest of the Home Alone kids?
We we did some digging, and found out what the now-fully-fledged adults look like, and what they are up to, these days.
Warning: this will make you feels SO OLD.
Macaulay Culkin (Kevin McCallister)
Macaulay Culkin, now 39 (I KNOW), shot to international stardom after his role as Kevin McCallister, even being nominated for the Best Actor Golden Globe after appearing in Home Alone 2: Lost in New York (1992) and topping numerous 'Greatest Child Stars' lists.
Macaulay took a break from acting in 1994 when he was 14, and returned in 2003 with an appearance on Will & Grace. Following this, Macaulay published an autobiography in 2006 titled Junior, and in 2013 he co-founded New York-based comedy rock band called The Pizza Underground. The actor dated Mila Kunis from 2002 to 2011.
These days, Macaulay lives in Paris where he's currently the CEO of satirical pop culture website Bunny Ears. He still takes on some acting from time to time, most recently reprising his role as Kevin in the Google Assistant advert, and in Seth Green's 2019 film, Changeland, where he met current girlfriend Brenda Song.
Devin Ratray (Buzz McCallister)
Devin Ratray played Kevin's mean older brother Buzz in Home Alone("I wouldn't let you sleep in my room if you were growing on my ass!" is one classic line), known for owning a pet tarantula and a ton of Playboys.
The actor, now 42, took on a few minor roles after the 1990 Christmas classic. Most notably, he appeared in a 2006 episode of Law & Order where he played murderer Richard Elm, and later rejoined the show to play an antagonist in and episode of Law & Order: Special Victims Unit.
In 2012, the actor played one of the trapped Wall Street business people in thriller Elevator, in 2013 he played Cole in Nebraska, and later the same year, Ben Gaffney in Blue Ruin. Among his stranger credits, in 2017, Devin filmed a documentary called Courting Condi which followed his attempts to seduce US Secretary of State Condoleezza Rice. O...k then!
Devin has been acting ever since, taking on roles in both TV and film alike. He most recent role was as Stephen in 2019 Hustlers, starring alongside Jennifer Lopez and Cardi B.
Buzz and J.Lo, whodda thought it?!
Angela Goethals (Linnie McCallister)
"You're what the French call les incompetents" - a perfectly scathing line delivered by Kevin's older sister Linnie McCallister, played by Angela Goethals.
Back when the film first came out in 1990, the actress was aged just 13, but was replaced by Maureen Elisabeth Shay when Home Alone 2: Lost In New York was released in cinemas two years later.
In 1996, Angela starred in her next role in a blockbuster film where she played Kathy Sanders in Jerry Maguire, alongside Tom Cruise and Renée Zellweger. In 1999, the actress graduated college with a bachelor's degree in French for which she is fluent.
Who knew her line in Home Alone would have such a profound affect on her?!
Since then, Angela has remained in the spotlight, taking on roles including in Comedy Central's Porn 'n Chicken, 1980s-themed sitcom Do Over - where she starred alongside You star Penn Badgley - Boston Public, Six Feet Under, Without a Trace, as rom-com Spanglish, 24, Grey's Anatomy, CSI and Crossing Jordan.
These days, 42-year-old Angela is a mum to seven-year-old and five-year-old daughters.
Michael C. Maronna (Jeff McCallister)
Jeff McCallister was Kevin's second oldest brother in the film, who granted kids everywhere a new withering put down to shoot at their siblings when he said: "Kevin, you're such a disease!"
The character was played by Michael C. Maronna, now 42, landed a few minor film roles post-Home Alone 1 and 2, including in Slackers (2002) and 40 Days and 40 Nights (2002). The following few years saw Michael star in a number of TV commercials and minor roles, before retiring from acting in 2004.
Since then, he's worked as an electrician on film and television sets with credits including Sex and the City and Be Kind Rewind.
Judging by Michael's Twitter, he now has a little boy (too cute) as well as co-hosting a weekly podcast, The Adventures of Danny and Mike.
Fuller McCallister (Kieran Culkin)
Fun fact: Fuller McCallister, Kevin's bed-wetting, spectacle-wearing little cousin, was played by Macaulay Culkin's IRL brother Kieran Culkin.
While Home Alone and Home Alone 2: Lost in New York were Kieran's first film roles, he continued acting well into adulthood starring in Father of the Bride (1991), and Father of the Bride Part II (1995), My Summer Story (1994), The Mighty (1998), She's All That (1999), The Cider House Rules (1999), The Dangerous Lives of Altar Boys (2002), Scott Pilgrim vs. the World (2010), and Movie 43 (2013).
Kieran enjoyed some success in adulthood, appearing in Oscar-nominated Music of the Heart and starring as the lead character in Igby Goes Down, for which he was nominated for a Golden Globe.
Most recently, Kieran has been working as a main cast member in HBO series Succession, now in its second season, playing Roman Roy. The actor was nominated for a Golden Globe for his role in 2018.
In 2013, he married Jazz Charton and the couple welcomed their first child, baby girl Kinsey Sioux in September 2019.
Fuller did good!
