The Hangover Part III trailer

The Wolfpack get up to more drunken, debauched antics in this boozy threequel!

An unexpected smash-hit on its release in 2009, The Hangover went on to gross more than $450 million worldwide. Combining rowdy, lads' humour with a comical mystery to solve, this story of men behaving badly spawned an even more successful sequel in 2011. Now the Wolfpack - comprising Phil (Bradley Cooper), Stu (Ed Helms), Alan (Zach Galifianakis) and Doug (Justin Bartha) - are up to no good once again. This time around, there's no wedding and no bachelor party - although an escape from a mental institution is reportedly involved! In the words of director Todd Phillips, "The Hangover Part III is Alan's story" - so expect something of a twist on the usual formula! However, when you factor in an expanded role for Ken Jeong as Mr Chow, you can rest assured the film won't be so sobering so much as totally outrageous!
