VIDEO: Watch 'The Hangover 2' teaser

Ready for another round?

Warner Bros. has released a teaser for the much-anticipated sequel to 2009 box office smash, "The Hangover."

Bradley Cooper, Ed Helms, and Zach Galifianakis reprise their roles in "The Hangover: Part II" with director Todd Phillips returning at the helm.

This time, the "Hangover" troupe find themselves in Bangkok, Thailand, for Stu's wedding.

Liam Neeson, who made headlines by replacing Mel Gibson in the role of the tattoo artist, co-stars in the film.

Written by Phillips, Scott Armstrong, and Craig Mazin, "The Hangover: Part II" is one of several R-rated comedies on the horizon. WB's "Horrible Bosses," starring Helms, Jennifer Aniston and Jason Bateman opens July 29 while Columbia's raunchy laffer "Bad Teacher," which stars Cameron Diaz and Justin Timberlake, bows June 24.

"The Hangover: Part II" hits theaters May 26.
