"The Hangover Part II" is a 2011 American comedy film directed by Todd Phillips. It is the sequel to the 2009 film "The Hangover" and the second installment in "The Hangover" film series.
The film follows the same group of friends, Phil Wenneck (Bradley Cooper), Stu Price (Ed Helms), and Alan Garner (Zach Galifianakis), as they travel to Thailand for Stu's wedding. However, after a night of partying, they wake up in a seedy Bangkok hotel with no memory of the previous night and Teddy, Stu's future brother-in-law, missing.
As they embark on a frantic search to find Teddy and retrace their steps, the group encounters various misadventures and absurd situations, including encounters with dangerous criminals, encounters with exotic animals, and run-ins with the Thai mafia.
"The Hangover Part II" received mixed reviews from critics, with some praising its humor and the performances of the cast, while others criticized it for being too similar to the first film and lacking originality. However, despite the mixed critical reception, the film was a commercial success, grossing over $586 million worldwide.
