The Hangover (franchise)

The Hangover is a series of three American comedy films written and directed by Todd Phillips, and starring Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha and Ken Jeong. All three films chronicle the misadventures of a quartet of friends, known as "the Wolfpack". While all of the films depict three of the four men on a mission to find their missing friend, the first two installments focus on the events following a night of debauchery before a wedding in Las Vegas and Bangkok, respectively. The third and final film, however, depicts a road trip and a kidnapping in lieu of a bachelor party.
