Yes, "The Hangover Part III" was released on May 24, 2013. It is the third installment in the Hangover film series, following "The Hangover" (2009) and "The Hangover Part II" (2011). In this film, the characters face a new adventure that does not involve a wedding or bachelor party but focuses on a rescue mission for one of their own, Alan. The movie concludes the trilogy and features the return of the original cast, including Bradley Cooper, Ed Helms, and Zach Galifianakis.

"The Hangover Part III" served as the conclusion to the trilogy, and there were no plans for a "Hangover 4" primarily because the filmmakers felt the story had reached its natural end. Additionally, the third installment received mixed reviews and underperformed at the box office compared to its predecessors, which may have influenced the decision not to pursue another sequel. Director Todd Phillips and the cast, including Bradley Cooper and Ed Helms, expressed interest in moving on to new projects rather than revisiting the franchise.

As of October 2023, "The Hangover Part III" is not available on Netflix. Streaming availability can change frequently, so it's a good idea to check directly on Netflix or other streaming platforms for the most current options. You may also find it available for rent or purchase on services like Amazon Prime Video, Google Play, or iTunes.

In "The Hangover Part III," Alan, played by Zach Galifianakis, goes missing. After a series of events, the group learns that he has been taken by a gangster named Marshall, portrayed by John Goodman. Alan's kidnapping is linked to a larger plot involving their friend Doug and the group's previous misadventures in Las Vegas. The film follows Phil, Stu, and Doug as they try to rescue Alan and confront their past while navigating the chaos of their lives.
