London: ‘The Hangover III’, the third film in the comedy movie series, will begin production in September. The film, starring Bradley Cooper, Zach Galifianakis and Ed Helms, is planned for release in May 2013, although a storyline is not yet known. "We are extremely pleased to have Todd Phillips and the guys back together again for another `Hangover` and we look forward to collaborating with them on another great movie," said Jeff Robinov, president of Warner Bros. Pictures Group. "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.
