Back in Vegas for their final bow.

We’ve known for awhile now that The Hangover: Part III, the final movie in the comedy trilogy, has been in the works since late last year. Word had come forth a few months ago that a summer filming date was possible, but other than that the idea was just kicked around as a September start seemed the most likliest. Warner Brothers setting a release date for the film in March certainly seems to have changed things  now, as a new report straight from Las Vegas says that the threequel will be returning to the gambling capital of the world, and that the laughs will also be headed to another party-heavy city.

The Las Vegas Sun reports that The Hangover Part III will begin to film at Caesar’s Palace and both on and off the Strip “within the month”. These locations are the same ones of the first film where The Hangover shot for 15 days. It’s also said that director Todd Phillips will be shooting most of the final film in Tijuana, which is something previously not revealed and gives the third movie a new location to take the cast of characters after their exotic Bangkok misfire.

The story sticks with the plot outline previously tossed around in which Stu (Ed Helms), Phil (Bradley Cooper), and Doug (Justin Bartha) seek to rescue Alan (Zach Galifiankis) from a mental hospital. It’s unclear exactly how this ties into a Vegas redux and Tijuana, but it will certainly be interesting to see.

The Hangover: Part III will be released on May 24th, 2013. This brings the comedy trilogy to a close just under four years after it premiered on Memorial Day weekend 2009. The Hangover: Part II saw a Memorial Day weekend opening in 2011 as well, and its where the comedy has done its absolute best so far. Both films combined have brought in a worldwide gross of $1 billion, and the final film will go up against action sequel Fast Six.
