Our favorite wolf pack is back for the conclusion to the 'Hangover' trilogy. Warner Brothers released the first official trailer to the final movie this morning. And by the looks of it, the guys will be getting in more trouble than they ever have before.

Bradley Cooper, Ed Helm, and Zack Galifinakas are back to put an end to one of the most epic trilogies in movie history. The preview shows some of our favorite characters from the previous movies, and new ones including characters played by John Goodman and funny woman Melissa McCarthy. This time there's no bachelor party or wedding, so what could possibly go wrong?
