The Hangover Part III (2013) Poster

Trivia

In every film of the trilogy, including this one, there are pigs somewhere. In The Hangover (2009), as Phil, Alan and Stu wake up in the trashed hotel suite, there is an inflatable pig in the bubble bath. In The Hangover Part II (2011), during the car chase through Bangkok, Chow crashes into a pig hanging on a meat stand and Stu gets covered in some of it. In The Hangover Part III (2013), Marshall's thugs wear pig masks.
