The Hollywood Reporter says that Bradley Cooper, Zach Galifianakis and Ed Helms are negotiating together to get $15 million each (against backend) to make The Hangover Part III. The trade adds that they are likely to get it with dealmaking wrapping up.
According to them, the three stars made under $1 million each for the first film, which grossed a massive $467 million worldwide. They then received around $5 million each for the sequel, which then grossed another $581 million worldwide. So, provided the third film is as successful, Warner Bros. should easily be able to recoup the money spent on the actors.
The studio is hoping to start filming the third installment, set in Los Angeles, this summer with Todd Phillips again directing for a Memorial Day 2013 release.
