The Hangover is a 2009 American comedy film, co-produced and directed by Todd Phillips and written by Jon Lucas and Scott Moore. The film stars Bradley Cooper, Ed Helms, Zach Galifianakis, Heather Graham, Justin Bartha, and Jeffrey Tambor. It tells the story of Phil Wenneck , Stu Price , and Alan Garner , who travel to Las Vegas for a bachelor party to celebrate their friend Doug Billings impending marriage. However, Phil, Stu, and Alan have no memory of the previous nights events and must find Doug before the wedding can take place.
Lucas and Moore wrote the script after executive producer Chris Benders friend disappeared and had a large bill after being sent to a strip club. After Lucas and Moore sold it to the studio for $2 million, Philips and Jeremy Garelick rewrote the script to include a tiger as well as a subplot involving a baby and a police cruiser, and also including boxer Mike Tyson. Filming took place in Nevada for 15 days, and during filming, the three main actors formed a real friendship.
The Hangover was released on June 5, 2009, and was a critical and commercial success. The film became the tenth-highest-grossing film of 2009, with a worldwide gross of over $467 million. The film won the Golden Globe Award for Best Motion Picture – Musical or Comedy, and received multiple other accolades. It is the tenth-highest-grossing film of 2009 in the world, as well as the second highest-grossing R-rated comedy ever in the United States, surpassing a record previously held by Beverly Hills Cop for almost 25 years. Out of all R-rated films, it is the third highest-grossing ever in the U.S., behind only The Passion of the Christ and The Matrix Reloaded.
A sequel, The Hangover Part II, was released on May 26, 2011, and a third and final film, The Hangover Part III, was released on May 23, 2013. Both sequels were box office hits, but were met with more negative reception from critics. (source : wikipedia)
