The Hangover - Watch Order: Release Order
The Hangover trilogy follows the misadventures of the Wolf Pack - Phil, Stu, Alan, and Doug - as they deal with the catastrophic aftermath of epic nights out. The first film establishes the formula of waking up with no memory and piecing together bizarre events, while the sequels expand on the group's bond and Alan's unpredictable nature.
The films progress chronologically, with each entry referencing previous adventures and deepening the characters' relationships. While each movie tells a complete story, the trilogy works best when watched as a complete journey.
