Here's the full trailer for 'The Hangover 2'.
The comedy sees the Wolfpack back in action for Stu's wedding in Bangkok, but as always, like in Las Vegas, things don't go to plan.
It seems that Doug goes missing once again in this film. Mike Tyson makes another cameo in the film too.
'The Hangover 2' is released on May 26th in the US and May 27th UK.
