Ed Helms, Zach Galifianakis, and Bradley Cooper were all casual acquaintances before the movie was filmed, which Helms said he believed helped in establishing a rapport and chemistry amongst their characters. Helms credited Director Todd Phillips for "bringing together three guys who are really different, but really appreciate each others' humor and sensibilities." Helms also said the fact that the story of the three characters growing closer and bonding, informed the friendship between the three actors: "As you spend fourteen hours a day together for three months, you see a lot of sides of somebody. We went through the wringer together, and that shared experience really made us genuine buddies."

By depicting and celebrating Las Vegas as the "ultimate guys' getaway," the film had a major impact on Caesar's Palace and Las Vegas. It was reported in 2013 that as of that year, guests continue to quote to Caesars staff two lines from the film's check-in scene: "Did Caesar live here?" and "Do you know if the hotel is pager friendly?" As a result of the film, Hangover-themed slot machines became popular at casinos throughout the Las Vegas valley, the Caesar's Palace gift shop sold tens of thousands of Hangover-related souvenirs, and the Las Vegas Convention and Visitors Authority received numerous inquiries from people interested in re-creating some of the film's most wild scenes, such as those involving a tiger.

According to Celena Haas (Caesar's Palace Director of Public Relations), the suite the characters stayed at was modelled after two of the resort's luxurious suites in its Forum Tower: a well-appointed penthouse, and the so-called "Rain Man (1988) suite," located on the 68th and 69th floors of the Forum Tower.

The plot was inspired by a real event that happened to Tripp Vinson, a Producer and friend of Executive Producer Chris Bender.

Zach Galifianakis improvised the line "I didn't know they gave out rings at the Holocaust". The initial line had Alan making a sexually inappropriate comment about Stu's mom, but Zach thought up the new line for two reasons: he wanted to show that Alan was someone who knew almost nothing about the world, and that a successful joke that mentioned the Holocaust would establish that the film was going to be hilarious overall. Everyone on-set loved the joke (Bradley Cooper appears to be disgusted by it, but he was actually following the script's directions for Phil to look at Alan in contempt, after the original line that was written out) and Todd Phillips said it would be in the film.

Regarding the explicit shots in the final photo slide show in which his character is seen receiving fellatio in an elevator, Zach Galifianakis confirmed that a prosthesis was used for the scene, and that he had been more embarrassed than anyone else during the creation of the shot. "You would think that I wouldn't be the one who was embarrassed; I was extremely embarrassed. I really didn't even want it in there. I offered Todd's assistant a lot of money to convince him to take it out of the movie. I did. But it made it in there."

During the scene where Phil, Stu, and Alan meet Chow in the desert, you can see their car pulling up in the reflection of Chow's sunglasses. This is a tribute to the scene in Casino (1995) where Nicky Santoro (Joe Pesci) meets Sam Rothstein (Robert De Niro) in the desert and you see the reflection of Santoro's car in Rothstein's sunglasses.

Ed Helms said that the most difficult day of shooting was the scene when Mr. Chow rams his car and attacks the main characters, which Helms said required many takes and was very painful, such as when a few of the punches and kicks accidentally landed and when his knees and shins were hurt while being pulled out of a window.

Such efforts were given an "Outstanding" rating by the American Humane Association for the monitoring and treatment of the animals.
