The gang are all back together for The Hangover 2 – and the trailer for the sequel has just landed.

Written by Scot Armstrong and directed by Todd Phillips, The Hangover 2 was made possible by the unexpectedly buoyant response to the first film, and Ed Helms, Bradley Cooper, Justin Bartha and Zach Galifianakis are all back on board for this one which is set to be released on the 26th of May this year.

Here’s a synopsis for you fine people,

In “The Hangover Part II,” Phil (Bradley Cooper), Stu (Ed Helms), Alan (Zach Galifianakis) and Doug (Justin Bartha) travel to exotic Thailand for Stu’s wedding. After the unforgettable bachelor party in Las Vegas, Stu is taking no chances and has opted for a safe, subdued pre-wedding brunch. However, things don’t always go as planned. What happens in Vegas may stay in Vegas, but what happens in Bangkok can’t even be imagined.
