The Hangover Part III

The Hangover Part III is a 2013 American comedy film. It serves as the third and final installment in The Hangover trilogy and the sequel to The Hangover Part II (2011). The film was co-produced and directed by Todd Phillips from a script he wrote with Craig Mazin and stars Bradley Cooper, Ed Helms, Zach Galifianakis, Ken Jeong, Justin Bartha, Mike Epps, Sasha Barrese, Gillian Vigman, Mike Vallely, Grant Holmquist, Jamie Chung, Sondra Currie, Heather Graham, Jeffrey Tambor, and Phillips reprising their roles from the previous two installments joined by Melissa McCarthy and John Goodman.

The film is darker in tone than the previous two instalments and follows the "Wolfpack" (Phil, Stu, Doug, and Alan) as they try to get Alan the help he needs after facing a mental breakdown, brought on from the bachelor party in Bangkok. However, things go awry when an incident from the original film comes back to haunt them.

The Hangover Part III was announced days before the release of The Hangover Part II and Mazin, who co-wrote Part II, was brought on board. In January 2012, the principal actors re-signed to star. In March 2012, Warner Bros. announced a U.S. Memorial Weekend release. The supporting roles were cast between June and September 2012. Principal photography began in September 2012 in Los Angeles, California before moving to Nogales, Arizona and Las Vegas, Nevada, concluding that November. The film had its world premiere on May 20, 2013, in Los Angeles, California, and was theatrically released worldwide on May 23, 2013, by Warner Bros. Pictures. At the box office, the film earned $362 million against a production budget of $103 million. It received generally negative reviews from critics, who found it a disappointing conclusion to the trilogy.
