WATCH: Hangover 3 Official Trailer!!

The final installment of The Hangover…The thirs installment in the popular movie franchise.

“The Hangover” franchise, which started as a surprise standalone hit during the summer of 2009, has turned in massive global phenomenon for the studio. The first two films grossed over $1 billion at the box office, and made stars of Bradley Cooper, Zach Galifianakis and Ed Helms — all of whom commanded massive salaries to return for the finale.

Picking up after the events of “The Hangover Part II” — Helms’ face tattoo now a distant memory — “Part III” brings Phil, Stu and Alan (Cooper, Helms and Galifianakis) back together after the death of Alan’s father (Jeffrey Tambor). Mayhem ensues, with John Goodman playing a murderous villain and Ken Jeong back as Mr. Chow because why not? The trailer also features brief glimpses of original co-star Heather Graham and franchise newcomer Melissa McCarthy.

“We’ve been on a lot of adventures together,” Alan says to Stu during the trailer, “but it seems like you haven’t learned anything.” During the next portion of the trailer, Alan seemingly decapitates a giraffe.

Watch “The Hangover Part III” trailer above. The finale arrives in theaters on May 24.
