'The Hangover' cast then and now

In June 2009, "The Hangover" was released. Ten years, two sequels and infinite belly laughs later, the original is a comedy classic. But its stars are in totally different places these days. Keep reading to find out what the cast of "The Hangover" is up to these days…

After years of taking on smaller roles in films, television shows and theater productions, Bradley Cooper's mainstream big break came when he played Phil Wenneck in "The Hangover." His character is the leader of the Wolfpack, a group of four friends who try to pick up the pieces after a Las Vegas bachelor party goes in an unexpected direction.

Since "The Hangover," Bradley Cooper's profile has only risen. He's starred in a number of hit films, garnering seven Academy Award nominations along the way — including three for best actor. Taken together, his movies have brought in almost $8 billion. His most notable project to date might be 2018's "A Star is Born," which he directed, starred in, co-wrote and produced, earning himself three Oscar nods. After a string of romances over the last decade with beauties including Jennifer Aniston, Renee Zellweger, Zoe Saldana and Suki Waterhouse, he started seeing model Irina Shayk in 2015. They welcomed a daughter, Lea, in 2017. But it wasn't meant to be: They called it quits in mid-2019.

Ed Helms played Stu Cena — and uptight dentist who gets out of control when he drinks — in "The Hangover." The film came at the height of Ed's celebrity when he was at the end of his run as a correspondent on "The Daily Show" and starring as Andy Bernard on "The Office."

Following the success of the first installation of "The Hangover," Ed Helms returned, along with the rest of The Wolfpack, for two sequels. He also remained on NBC's "The Office" until the end of its run in 2013. Another high-profile role came in the animated 2017 film "Captain Underpants: The First Epic Movie," when he provided the voice for the title character. Ed's become somewhat of a regular on the college graduation circuit in recent years, speaking at commencements for Knox College, Cornell University and the University of Virginia. On a January 2018 episode of Anna Faris's "Unqualified" podcast, Ed offered a rare soundbite on his personal life: "I've been married a couple years and she's fabulous and she enjoys a lot more anonymity than I do."

Before "The Hangover," Zach Galifianakis (left) was a regular on the comedy scene, landing spots on shows on networks like VH1, Comedy Central and Cartoon Network. It wasn't until he played the lovably immature brother of the bride, Alan Garner, in "The Hangover," though, that he found mainstream visibility and fame.

Zach Galifianakis has taken on both high-profile and cult-hit roles since "The Hangover." He starred on three seasons of HBO's "Bored to Death" and earned critical acclaim for his turn in the 2014 ensemble movie "Birdman." More recently, his long-running Funny or Die interview show, "Between Two Ferns with Zach Galifianakis," was set to become a Netflix movie. He married Quinn Lundberg in 2012, with whom he has two children.

Justin Bartha's Doug Billings provided the premise for all the fun in "The Hangover," as he was the groom-to-be who's being celebrated in Vegas. Previously, he was best known for starring in the two "National Treasure" movies and dating Ashley Olsen.

Post-"The Hangover," Justin Bartha's resume has been heavy on theater, including turns in plays by Zach Braff and Jesse Eisenberg. He's also landed roles on network shows like "The New Normal" and "The Good Fight." He and fitness instructor Lia Smith got hitched in 2014 and welcomed daughter named Asa Charlotte later that spring.

Going into "The Hangover," the most established star was arguably Heather Graham, who played kind-hearted stripper Jade. Heather had already spent decades in the entertainment business with major roles in flicks like "Boogie Nights," "Austin Powers: The Spy Who Shagged Me" and "Bowfinger."

Though Heather Graham didn't appear in the second "Hangover" film, she did reprise her role in the third and final installment. Since then, she's continued to take on TV and film roles, including a turn on the last season of "Californication." 2018 marked her directorial debut with the movie "Half Magic," which she also wrote and starred in.

Every movie needs a bad guy, and in "The Hangover," that person is Ken Jeong's gangster, Mr. Chow. Though trained as a doctor, Ken found his true calling as a comedian and actor during med school in the '90s. Before "The Hangover," he'd had parts in films like "Knocked Up" and "Pineapple Express."

Another of Ken Jeong's most famous roles, Señor Chang on the sitcom "Community," came soon after the first "Hangover" film in 2010. In 2015, the sitcom "Dr. Ken," which Ken wrote, produced and starred in, debuted on ABC. The show lasted for two seasons. In 2019, he released his first comedy special on Netflix, "You Complete Me, Ho," which is in many ways a love letter to his wife, fellow physician Tran Ho, with whom he has twin girls.

Four years after the end of his career in the ring, champion boxer Mike Tyson made an appearance as himself in "The Hangover." He played a heightened version of himself in the film, in which he owns of a tiger that gets stolen from his house in the middle of the night by the Wolfpack (long story).

Since his most famous film cameo, Mike Tyson has remained in the spotlight through various promotions, entertainment projects and charity work. In 2013, he worked with Spike Lee to bring his one-man show "Mike Tyson: Undisputed Truth" to 36 cities across the country and HBO. He's also launched a foundation to help kids from challenging backgrounds, written two memoirs, starred on an eponymous animated mystery series on Adult Swim and been the face of an Australian car service franchise — among many other sundry projects.

The go-with-the-flow drug dealer in "The Hangover," Black Doug, who was played by Mike Epps, was inadvertently responsible for the Wolfpack's Vegas misadventures: He accidentally sold Alan roofies instead of ecstasy. This turn for Mike — seen here with then-wife Mechelle at the movie's June 2090 premiere — came after roles in film series like "Friday" and "Resident Evil."

Mike Epps has continued to show up in films and on TV since "The Hangover," including as one of the villains in "The Hangover III." In 2010, he put out the stand-up special "Under Rated & Never Faded" and performed hosting duties at the BET Hip Hop Awards. Though usually cast in comedic roles, in 2012, Mike received positive buzz for his dramatic turn in "Sparkle." In 2020, he's set to appear in the final "Friday" installment, "Last Friday." IN May 2018, less than a year after divorcing his wife of 12 years, Mechelle, he got engaged to girlfriend Kyra Robinson, BET reported.

Years of bit parts in movies like "American Pie" and "Legally Blonde" and TV shows like "Boy Meets Girl" and "CSI: Miami" led Sasha Barrese to her most famous role yet: Tracy Billings, fiancée-turned-wife of Wolfpack member Doug, in all three "Hangover" movies.

Sasha Barrese's acting career slowed soon after the last "Hangover" flick, and in 2014, she made a major career shift and became a professional poker player. Since then, she's competed in a variety of tournaments, including several World Series of Poker events, and has climbed to 23rd on the all-time money list in her native Hawaii.

Rachael Harris (seen here at the movie's 2009 premiere) showed up in "The Hangover" as Melissa, Stu's unlikable and domineering girlfriend. This was her last appearance in the franchise, since by the end of the first movie, the usually wimpy Stu had finally summoned the courage to end the relationship. This was Rachael's second time appearing opposite Ed Helms: The two also were correspondents together on "The Daily Show" in the early 2000s.

The television and film roles have continued to flow in for Rachael Harris since "The Hangover." Notable castings include the main character's mom in the "Wimpy Kid" franchise films, a recurring spot on "Suits" and Lucifer's therapist on "Lucifer." She eloped with violinist Christian Hebel in 2015. They soon welcomed two boys, Henry in 2016 and Otto in 2018.
