The stars will reunite for the third go-around with director Todd Phillips, who says, "I'm so excited to embark on another Hangover film with Bradley, Ed and Zach. We're going to surprise a lot of people with the final chapter we have planned. It will be a fitting conclusion to our three-part opera of mayhem, despair and bad decisions."

EXCLUSIVE: ET in Exotic Bangkok for 'The Hangover Part II'

No word yet on whether or not Justin Bartha will be part of the festivities – or sidelined again. The first Hangover saw the friends celebrating the upcoming marriage of Bartha's character in Las Vegas, only to find the Wolfpack retracing their outrageous steps from the night before in search of their missing friend. The Hangover Part II followed a similar course, only this time it was in Bangkok for the wedding of Ed Helms' character.

Production on The Hangover Part III is projected to begin in September.
