'The Hangover' at 15: Here are 15 things you may not know about the comedy

The Viva Las Vegas Wedding Chapel, meanwhile, offers a “Hangover”-themed wedding package that includes a ceremony officiated by an Alan impersonator, and Jägermeister shots for the couple, for $950. A Stu impersonator is available for an extra $150.

9. Jade’s apartment complex? That’s the Wild Wild West Gambling Hall, the one-time site of the Athletics’ proposed stadium, which Station Casinos closed in 2022.

10. During a break in filming, Cooper, Phillips and Graham went to see Cirque du Soleil’s “Zumanity” at New York-New York.

Despite what Graham said were assurances by “Zumanity” staff that they’d be left alone, Cooper ended up shirtless, being rubbed all over by cast members, during the show.

“They were like, ‘We’re not gonna take you guys up onstage,’ ” Graham told us in 2009. “We were like, ‘Oh good.’ And then they grab Bradley, take his shirt off, and he’s like, ‘Ohhh!’ Really freaking out.”

11. As written, Ken Jeong’s Mr. Chow was supposed to be introduced in his underwear. Jeong suggested the scene, filmed in the vacant lot at Mandalay Bay Road and Giles Street, should be done in the nude.

“When Ken jumped out of the trunk, there was a policeman who said that people were complaining from Mandalay Bay, which was in no way true,” Phillips told the Hollywood Reporter in 2013. “He said, ‘You keep doing it, and we’re going to shut you down.’”

According to Helms, the cop said something like, “This is Vegas — we don’t act like that. This is not that kind of town.”

“Behind the cop, as he’s saying this,” Cooper added, “is a billboard of naked women.”

12. The scene in which the guys bring Chow his money is a direct homage to the desert meeting between Sam “Ace” Rothstein (Robert De Niro) and Nicky Santoro (Joe Pesci) in “Casino” — down to the reflection of the arriving Mercedes in Chow’s sunglasses. Both scenes were filmed at the Jean Dry Lake Bed.

13. A 1965 Mercedes-Benz 220SE that was wrecked for the movie is on display in Las Vegas. The car has no wheels, and its interior is destroyed as if by the tiger. It can be seen at the Hollywood Cars Museum, 5115 Dean Martin Drive.

14. The movie grossed $277.3 million domestically, besting 1984’s “Beverly Hills Cop” to become the highest-grossing R-rated comedy ever. It’s since been surpassed by “Deadpool” ($363.1 million) and “Deadpool 2” ($324.6 million).

15. Cooper auditioned for Phillips’ 2004 comedy “Starsky & Hutch,” but the duo didn’t really bond until the casting process for “The Hangover.” They went on to produce the movies “War Dogs” (2016), “A Star Is Born” (2018) and “Joker” (2019) together. Since “The Hangover,” Cooper has 12 Oscar nominations while Phillips has three.
