In the aptly-titled 1990 holiday comedy 'Home Alone,' young Kevin McAllister (Macaulay Culkin) is accidentally left, well, home alone. When his family goes to France for their vacation, what begins as an adult-free party week for the 8 year-old boy turns into a battle when Kevin is forced to use his wits and cunning to defend the home from would-be burglars, played by Joe Pesci and Daniel Stern. This wacky and heartwarming comedy became an instant holiday classic, spawning an immediate sequel -- and a few more lame, direct-to-DVD entries. Twenty-three years later, we check in with the cast of the film to see what they're up to now.

Then: Macaulay Culkin was just getting his young career started when he played 8 year-old Kevin McAllsiter, the film's protagonist who is accidentally left home alone during Christmas and must defend his house from would-be robbers. He had previously appeared in 'Uncle Buck' with John Candy, who made a cameo in 'Home Alone.' John Hughes, who wrote 'Uncle Buck,' specifically wrote the part of Kevin McAllister for Culkin -- two years later, Culkin would reprise the role for 'Home Alone 2: Lost in New York.'

Now: Culkin went on to appear in several '90s films, including 'My Girl,' 'The Good Son,' and 'Richie Rich,' and then took some time off. He went the edgy route with roles in films like 'Party Monster,' in which he played infamous nightclub promoter and murderer Michael Alig, and 'Saved,' a darkly comedic satire of evangelical Christian teens with Mandy Moore and Jena Malone. He's lent his voice to several episodes of 'Robot Chicken,' created by his 'Party Monster' co-star Seth Green,' but these days acting isn't a priority. He's involved in an art collective called Three Men and a Baby with musician Adam Green, and recently debuted his music project: The Pizza Underground, a Velvet Underground cover band that changes the lyrics to the band's classics to make them about pizza.

Joe Pesci, Harry

Then: Joe Pesci played Harry, the shorter member of the Wet Bandits burglars who attempt to rob the McAllister home on Christmas Eve. Robert De Niro, who previously appeared with Pesci in 'Raging Bull' and 'Goodfellas,' turned down the role of Harry.

Now: Pesci went on to star in 'JFK,' 'My Cousin Vinny,' and reunited with De Niro and Scorsese for 'Casino' in 1995. He reprised the role of Leo Getz for 'Lethal Weapon 4' in 1998, then took a break from acting until 2006, when his old pal Robert De Niro got him to make a cameo in his film 'The Good Shepherd,' which De Niro directed. Since then, he's only appeared in the 2010 film 'Love Ranch' and in a Snickers commercial.

Daniel Stern, Marv

Then: Daniel Stern played Marv, the taller, dumber half of the Wet Bandits. He was most familiar to audiences as the narrator of the series 'The Wonder Years,' and had appeared in films like 'Diner' and 'Little Monsters.'

Now: Stern's film credits include both 'City Slickers' films, 'Bushwhacked,' 'Very Bad Things,' and Drew Barrymore's directorial debut 'Whip It.' Recently, he appeared in episodes of 'Workaholics,' 'Family Guy,' 'Girlfriend in a Coma,' and the new HBO series 'Getting On.' He also starred in 'A Christmas Story 2,' the straight-to-DVD sequel to the holiday classic.

John Heard, Peter McAllister

Then: John Heard played Peter McAllister, Kevin's father. Among the actors considered for the part were high profile names like Michael Douglas, Kevin Costner, Harrison Ford, Bill Murray, Chevy Chase, and Tom Hanks. Heard was cast because director Christopher Columbus liked his performance in the film 'Cutter's Way.'

Now: Heard has a massive resume that includes diverse films like 'Pelican Brief,' 'Pollock,' 'O,' and 'White Chicks.' He's starred in several films in 2013 alone, including 'Sharknado,' 'Assault on Wall Street,' and 'Runner Runner.' His TV credits include 'Battlestar Galactica,' 'Southland,' and 'Entourage,' and he recently made an appearance on Adult Swim's 'Tim and Eric's Bedtime Stories.'

Catherine O'Hara, Kate McAllister

Then: Catherine O'Hara, star of 'Beetlejuice,' played Kevin's mother, Kate. She had previously appeared in 'After Hours' with John Heard. Like the part of Kevin's father, several more high profile names were considered for her role, including Sigourney Weaver, Diane Keaton, and Geena Davis.

Now: O'Hara became a regular in the films of Christopher Guest, appearing in 'Waiting for Guffman,' 'Best in Show,' 'A Mighty Wind,' and 'For Your Consideration.' She recently reunited with 'Beetlejuice' director Tim Burton to lend her voice to 'Frankenweenie,' appeared in 'A.C.O.D.' with Adam Scott and Richard Jenkins, and currently voices a role on the animated series 'Glenn Martin DDS.'

Devin Ratray, Buzz

Then: Devin Ratray played Buzz, Kevin's brother who terrifies him with his pet tarantula and a photo of his girlfriend ("Buzz, your girlfriend. Woof.") He previously had a minor role in 'Little Monsters' with Daniel Stern.

Now: Ratray has enjoyed a consistent career, appearing in films like 'The Prince and Me' and 'Surrogates,' and episodes of 'Law and Order' and 'Supernatural.' 2013 has been a big year for the actor, though, with small supporting roles in 'Side Effects,' 'R.I.P.D.,' 'Nebraska,' and the acclaimed indie 'Blue Ruin,' which has been playing the festival circuit.

Mike Maronna, Jeff

Then: Mike Maronna made his acting debut as Jeff, another one of Kevin's brothers who constantly give him grief.

Now: You know him best as Big Pete from the '90s Nickelodeon series 'The Adventures of Pete and Pete.' Following that, he appeared in the films 'Slackers' and '40 Days and 40 Nights.' Maronna went to college and became a professional electrician -- he's worked on the films 'Runner Runner,' 'Men in Black 3,' and 'The Sitter,' and on the CBS series 'Elementary.' He recently completed work on the upcoming HBO film 'The Normal Heart.'

Hillary Wolf, Megan

Then: Hillary Wolf played Megan, Kevin's sister. Her previous work had all been in TV movies, including 'I'll Take Manhattan' with Valerie Bertinelli. 'Home Alone' marked her feature film debut -- she would go on to reprise the role of Megan for the sequel and appear in the film 'Big Girls Don't Cry ... They Get Even.'

Now: Wolf left acting to pursue her passion for judo. She won the world judo championships for juniors in 1994, and represented the United States in judo at the 1996 Summer Olympics and at the 2000 Olympics. Wolf then retired from competing and went to college, married, and had kids. She now owns the Wolf Judo Academy in Colorado Springs, where she instructs children.

Kieran Culkin, Fuller

Then: Kieran Culkin, younger brother of Macaulay, played Kevin's cousin, Fuller, who had quite the fondness for Pepsi. Like several of the other kids, Kieran Culkin was also making his acting debut in the film. Around the same time, he starred in both 'Father of the Bride' films and reprised the role of Fuller for 'Home Alone 2.'

Now: Culkin went on to star in 'She's All That,' 'Igby Goes Down,' and 'Scott Pilgrim vs. the World.' Recently, he's appeared in the films 'Margaret' and 'Movie 43,' and in the 2012 Sydney Opera House production of 'This is Our Youth.' He can be seen next in the film 'Quitters' with Mira Sorvino.
