Warner Brothers has finally released full length theatrical trailer for The Hangover Part II.

The Hangover Part II is director Todd Phillips‘ follow-up to 2009’s smash hit The Hangover, which became the highest-grossing R-rated comedy of all-time. Reprising their roles from The Hangover, Bradley Cooper, Ed Helms, Zach Galifianakis, and Justin Bartha star in the film. Ken Jeong, Jeffrey Tambor, and Mike Tyson also rejoin the cast.

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.

The Hangover Part II was filmed in Los Angeles, and on location in Thailand and will be released to theaters on May 26th, 2011.
