Bartha mostly spent the five years after National Treasure popping up in romantic comedies and dramas, including Trust the Man starring Julianne Moore, the Sarah Jessica Parker-starring Failure to Launch, and ensemble rom-com New York, I Love You, which basically stars every actor with a SAG membership. And, of course, National Treasure: Book of Secrets.

But in 2009, Bartha got his biggest big break when he landed a part in what at the time must have seemed like just another bromance comedy: The Hangover. Bartha plays a groom who goes missing during his bachelor party in Las Vegas, which meant he actually didn't get that much screen time or opportunity to be funny. However, the movie was the hit of the summer, turning its cast into instantly recognizable faces, and eventually leading to two sequels (although we may never get to see The Hangover 4.)

If you missed The Hangover bandwagon but you know Bartha from somewhere, chances are you're someone who loves a quiet little indie drama. Outside the franchise, Bartha has mostly stuck to these kinds of projects.

In 2010 Bartha played a drug-dealing Hassidic Jew opposite Jesse Eisenberg in Holy Rollers. He played New York punk artist Stiv Bator in CBGB, a movie about the iconic New York punk club that reunited Harry Potter's Alan Rickman and Rupert Grint. In 2016 he played Rose Leslie's boyfriend in a movie called Sticky Notes (or The Backup Dancer), which also starred Ray Liotta. And in 2018, he starred in dark comedy Sorry for Your Loss, playing a man whose estranged father challenges him to scatter his ashes at his favorite football stadium in exchange for his inheritance.
