The Hangover Part II structure. There needs to be a ticking clock, there needs to be a missed night and there needs to be someone who's gone and a woman who is waiting to get married and a guy who needs to get married." In June 2010, before accepting the Guy Movie of the Year award on the Spike Guys Choice Awards, Phillips announced that there would be a "Hangover 2" and that they were hoping to begin filming around October 15, 2010, for a July 4, 2011 weekend release. In July 2010, it was confirmed that film would indeed be set in Thailand
The Hangover (film series) opts for a safe, subdued pre-wedding brunch. However, things do not go as planned, resulting in another bad hangover with no memories of the previous night. Once again someone is lost, this time Stu's future brother-in-law, and Phil, Stu, and Alan search for him in Bangkok. Warner Bros. hired Todd Phillips and Scot Armstrong to write a sequel to "The Hangover" after a trailer brought down the house at ShoWest in April 2009, two months before the film was released. The principal actors were cast in March 2010 to reprise their roles from the first film. Production began in October
