'The Hangover 3': Buddy comedy to return to Las Vegas

The boys are back in town.

Bradley Cooper, Zach Galifianakis and Ed Helms are coming back to Las Vegas to shoot "The Hangover, Part 3," this according to the Las Vegas Sun. The three will be joined by Mike Tyson, who has previously been confirmed to reprise his role as Mike Tyson. 

As for the story, it appears that at least one storyline will involve the three rescuing a friend from a mental hospital. The picture, directed by Todd Phillips, will shoot in Tijuana (what could go wrong there?) and in Los Angeles as well.

The first two "Hangover" films have earned more than $1 billion combined. So it only seems to make sense that they'd make a third. The movie has an expected release date of May 24, 2013.
