Contract negotiations for the third, and rumored final, installment of "The Hangover" films are nearing their end and it looks like Warner Bros. might end up dropping $15 million a piece to the movie's three main stars, Bradley Cooper, Zach Galifianakis and Ed Helms.

For the first film, the three stars each made less than a million each with Bradley Cooper making the highest being the most recognizable name at the time.  When "The Hangover" became the highest grossing rated R comedy of all time with $467 million, Warner Bros. was quick to shell out the money for a sequel, paying the three actors a base salary of $5 million each along with back end compensation that has reportedly raised their take to the teens after the sequel made over $580 million, breaking the record set by the original.

The three actors are all represented by by CAA and entered into negotiations as a team.  One insider said that the deal will most likely be accepted as "The Hangover" is a proven brand, something that is rare in Hollywood today.  As long as the deal is reached on time, shooting for the next film will start this summer with a planned Memorial Day 2013 release.  Early reports are that the next film will take place entirely in Los Angeles and depart from the formula used in the first two films.
