The year's funniest movie is less than two months away, and we have a first look at the official poster for 'The Hangover Part II' featuring Bradley Cooper, Zach Galifianakis and Ed Helms -- and a monkey. But where's Justin Bartha? The mystery deepens…

In 'The Hangover Part II,' Phil (Cooper), Stu (Helms), Alan (Galifianakis) and Doug (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.

Once again directed by Todd Phillips, 'The Hangover Part II' hits theaters May 26.
