The Hangover 2 is created by the original team and continues the funny style of the previous episode. Stu (Ed Helms), who experienced emotional entanglement in the previous episode, is newly married in this episode. His friends Phil (Bradley Cooper), Alan (Zach Galifianakis) and Doug (Justin Bartha) go to Thailand to attend his wedding. Unexpectedly, the Hangover incident happened again. A group of brothers woke up and found themselves in Bangkok. The bride's brother (Chun Lee) mysteriously disappeared. The Asian gangster "Mr. Zhou" (Ken Jeong) suddenly appeared, so a crazy adventure in a foreign country came back again! It is worth mentioning that Ang Lee's son Chun Lee played the bride's brother in the film, a top student with excellent grades.
