What is hangover trilogy?

The Hangover trilogy is a series of three comedy films directed by Todd Phillips. The trilogy consists of "The Hangover" (2009), "The Hangover Part II" (2011), and "The Hangover Part III" (2013).

The first film follows four friends who travel to Las Vegas for a bachelor party and wake up the next morning with no memory of the previous night, along with a missing groom. The group then embarks on a wild and hilarious journey to find their friend and piece together the events of the night before.

The second film takes the group to Thailand for another bachelor party, with similar consequences and hijinks as the first film.

The third film deviates from the formula of the first two movies and follows the group as they seek to intervene in a dangerous situation involving their friend, Alan, played by Zach Galifianakis.

The films are known for their outrageous humor, memorable performances from the main cast (including Bradley Cooper, Ed Helms, and Ken Jeong), and unexpected twists and turns. The trilogy has been both a critical and commercial success, with the first film in particular being a breakout hit.
