'Hangover 3' Trailer Release: First Official 'Hangover III' Trailer Shows Epic Adventure, The Wolfpack is Back Along with Melissa McCarthy [VIDEO]

This first official "Hangover 3" trailer has finally been released! In the third installment of the blockbuster comedy trilogy, it looks like the "Wolf Pack" are getting themselves into a world of trouble. Judging by the two minute trailer released Thursday on Warner Bros. YouTube page, it looks like Zach Galifianakis, Bradley Cooper, and Ed Helms' characters are going back to Las Vegas and they are ready to "burn it down." Get ready "Hangover III" fans, the "Wolf Pack" are heading to Las Vegas one last time as the movie hits theaters Memorial Day weekend.

The trailer opens with the group of trouble makers at a funeral, presumably for Alan's dad. Galifianakis is singing at the funeral and doing a magnificent job. From there the chaos begins including guns, car crashes, and explosions. Not to give too much away, (watch the official trailer below) there is what most likely will be an epic scene with a giraffe, Alan, and a overpass.

There even is a rumor put to rest in the trailer. Melissa McCarthy is indeed in "Hangover 3." This is great news, because quite frankly, she is perfect for the "Hangover" trilogy. Also new to the third movie is John Goodman, who looks like he will be playing the main bad guy.

Coming back for "Hangover 3" is Heather Graham, Ken Jeong, and even Mike Tyson is back playing himself. The movie is set to open in theaters May 24. It will likely be another box office blockbuster, opening up the summer movie season.

It definitely seems like Ken Jeong's character, Mr. Chow, will have a big part in the third movie. He has already been featured on the movie poster and was seen numerous times in the first official trailer.

Are Mstarz readers excited for "Hangover 3?" It definitely looks like it will involve a lot of "epic" scenes and raunchy comedy. If you liked the first two movies, you are probably going to love the third part of the trilogy. Enjoy the first official trailer for "Hangover 3."
