It's been more than 10 years since 'Old School' hit theaters, so we thought it would be a good time to take a look back at this classic comedy. 'Old School,' about a group of older guys who start a fraternity with outcasts from a local college, is a comedy classic that still holds up today. Let's take a peek at what Vaughn and the rest of the cast looked like back then, and see where they are now.

Then: Dreamy actor Luke Wilson (brother of Owen Wilson) played straight guy Mitch Martin, who gets suckered into starting a fraternity so he can keep his house.

Now: Wilson has had roles in Wes Anderson films, including 'The Royal Tenenbaums' and 'Bottle Rocket,' and recently starred in the short-lived TV series 'Enlightened.' He can be seen in 'Anchorman 2: The Legend Continues,' reprising his role of Frank Vitchard, one of Ron Burgundy's (Will Ferrell) rival newsmen.

Then: The fast-talking and charismatic actor didn't sign his contract to be in 'Old School' until the first day of shooting, during a wedding scene.

Now: Vaughn has made a career out of playing the same kind of character over and over again, and you can see his latest comedic efforts in 'The Internship,' which he co-wrote. The film also stars Owen Wilson, brother of 'Old School' co-star Luke Wilson. He can be seen next in 'Delivery Man' (coming out November 22) and 'Anchorman 2' (coming out December 20).

Then: 'SNL' star and comedy genius Will Ferrell stars as Frank "The Tank" Ricard, and though he's trying to stay sober for the sake of his new marriage, he can't help but let his friends get him into trouble.

Now: After leaving 'SNL,' Ferrell's career went huge: he's starred in 'Step Brothers,' 'Elf,' 'The Other Guys' and, of course, 'Anchorman.' You can see him in the sequel, 'Anchorman 2: The Legend Continues,' this winter. The actor also produced and stars in the upcoming IFC miniseries 'The Spoils of Babylon,' which also features Kristen Wiig and Tobey Maguire. There was talk of an 'Old School' sequel a few years after the first film, but Ferrell was very vocal about not wanting to participate. He will, however, be reuniting with his 'Step Brother' co-star John C. Reilly for the Halloween comedy 'Devil's Night.'

Jeremy Piven, Dean Gordon Pritchard

Then: Like his 'Old School' co-star Vince Vaughn, Jeremy Piven was also known for playing fast-talking, charismatic types in movies. He previously starred in another college-set film, 'PCU.'

Now: Piven is known best for his work as agent Ari Gold on the HBO series 'Entourage.' There's been talk of a movie for some time now -- which is said to be held up because of monetary disputes between the cast and producers -- but in the meantime, you can catch him on the PBS series 'Mr. Selfridge,' the Tom Cruise-starring sci-fi flick 'Edge of Tomorrow' and 'Sin City 2,' dubbed 'A Dame to Kill For.'

Then: Following small roles in film and TV, Ellen Pompeo caught her big break as Luke Wilson's love interest in 'Old School.'

Now: Pompeo went on to star in 'Grey's Anatomy,' ABC's long-running medical drama series, in which she plays title character Dr. Meredith Grey.

Juliette Lewis, Heidi

Then: Juliette Lewis already had a long and varied career under her belt, starring in everything from 'National Lampoon's Christmas Vacation' to Martin Scorsese's 'Cape Fear.' For 'Old School,' Lewis yukked it up as Mitch's cheating girlfriend in a small but memorable role.

Now: In addition to acting, Lewis fronted her own band called Juliette Lewis and the Licks until 2009. She continues to act, and you can see her next in 'August: Osage County.' In her personal life, Lewis is a member of the Church of Scientology. The actress has also scored on role on M. Night Shyamalan's upcoming series 'Wayward Pines.'

Leah Remini, Lara Campbell

Then: Like many of her roles, Leah Remini plays a no-nonsense wife in 'Old School,' married to Vince Vaughn's character. Prior to starring in the film, Remini had early gigs on 'Charles in Charge' and 'Saved by the Bell.' She also auditioned for the part of Monica Gellar on 'Friends' before it ultimately went to Courteney Cox.

Now: Remini is known best for her role on long-running sitcom 'The King of Queens' as the (wait for it) no-nonsense wife of Kevin James' character. She was one of the hosts on 'The Talk' until 2011 and was a vocal Scientologist. While she left earlier this year without providing a public explanation for her departure, she's having a hard time cutting the religion from her life -- she recently got subpoenaed to testify in a lawsuit against the Church of Scientology, which she's not too happy about. Remini is currently a contestant on 'Dancing with the Stars.'

Elisha Cuthbert, Darcie

Then: Before appearing in 'Old School' as the teenage girl Luke Wilson unwittingly sleeps with, Elisha Cuthbert had started making a name for herself as the daughter of Kiefer Sutherland's character on '24.'

Now: Cuthbert got pretty famous after 'Old School' and went on to have a bigger role in the film 'The Girl Next Door.' Most recently she starred on the sitcom 'Happy Endings,' which was unfortunately canceled after only three seasons. An avid hockey fan, Cuthbert is currently engaged to NHL player Dion Phaneuf.

Then: Known best for his role as Stifler in the 'American Pie' movies, Seann William Scott had a small, but hilarious role in 'Old School' as a petting zoo wrangler at Bernard's kid's birthday party.

Now: Scott surprised everyone last year with sleeper hit 'Goon,' a dark comedy about a hockey player who packs a serious punch, but he's been featured in 'The Dukes of Hazzard,' the 'Ice Age' movies, 'Planet 51' and the star-studded 'Movie 43' since his 'Old School' days. Though he failed to surprise everyone when he reprised his Stifler role for the fourth time in 2012's 'American Reunion,' he recently boarded the action-comedy 'Skiptrace' opposite Jackie Chan and Fan Bingbing.

Then: Helberg played one of the geeky fraternity members. He had previously played nerdy roles in 'Undeclared' and 'Van Wilder,' and was a cast member on 'Mad TV.'

Now: Helberg is best known for his role as Howard Wolowitz on 'The Big Bang Theory,' though some other notable credits include 'Reno 911!,' 'Arrested Development,' 'Evan Almighty' and Funny or Die's 'Drunk History.' Few actors have made a better career out of playing gigantic nerds.
