Get ready for more obscene laughter in 'The Hangover Part II' as Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha head to Thailand for more trouble. 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. The wolfpack is once again directed by Todd Phillips.
