His background in dramatic roles prior to The Hangover helped shift audience perceptions of him as a purely comedic actor. Off-screen, Cooper’s involvement contributed to the film’s heightened profile and financial success, establishing him as a leading man capable of anchoring a studio comedy.
Ed Helms as Stu Price
Ed Helms plays Stu Price, the cautious dentist and soon-to-be stepfather who enters the trip hesitant and exits exhausted. Helms is known for meticulous preparation and subtle physical comedy, which informs Stu’s steady presence amid the frenzy. His casting brought a grounded, everyman quality to the group, and his performance is often cited as a highlight in balancing the film’s more absurd moments.

Justin Bartha as Doug Billings
