Hangover Part 3 trailer released, watch below. The Hangover Part III first teaser trailer has premiered. Bradley Cooper, Ed Helms, and Zach Galifianakis are back, with the action returning to Las Vegas. The Hangover 3 trailer starts with Alan (Zach Galifianakis) singing angelically at his father’s funeral, which confirms director Tod Phillips’ statements about the film previously.
Phil (Bradley Cooper) and Stu (Ed Helms) listen intently. The one cast member who appears to be missing is Doug (Justin Bartha), although his wife is in attendance at the funeral. The film seems to focus around Cooper, Helms and Ken Jeong who plays Mr. Chow. Who would ever forget the famous naked Mr. Chow flying out the trunk of their car in the first “Hangover”?
