This release combines the hilarious first two entries of the Hangover series, following the exploits and misadventures of a wild pack of friends (Bradley Cooper, Ed Helms, Zach Galifianakis, and Justin Bartha). In 2009's The Hangover, a blowout Las Vegas bachelor party turns into a race against time when three hung-over groomsmen awaken after a night of drunken debauchery to find that the groom (Bartha) has gone missing, and attempt to get him to the alter in time for his wedding. In 2011's The Hangover II, it's Stu's (Helms) turn to tie the knot, and the gang take their mishaps to Thailand for an unforgettable weekend in Bangkok.
