A few weeks ago we reported that Warner Bros. hired The Hangover Part II writer Craig Mazin to pen the script for The Hangover Part III. While little is known about the story, actor Zach Galifianakis recently chimed in with a few details. Here's an excerpt from a recent article below, which includes possible plot points for The Hangover Part III.

"They want to do a Hangover III," he says. "I'm getting fricking phone calls already." According what he's heard, the plot ditches the format of the first two and focuses on his character escaping from a mental institution with help from the wolf pack."

Last month, Craig Mazin himself offered a few plot scenarios, and indicated that The Hangover Part III will be the last in the franchise.

"I cannot image a worse hangover than the one they experience in Bangkok. That's it. No more. The third one really has to be about something that gets them off of this cycle. Every time these three guys get together, something terrible happens. The third one is about saving them from a life of agony. Sometimes you are caught between a rock and a hard place. Sometimes, people are going to ding you for being too similar. They are going to ding you for straying. If it ain't broke, why fix it? This isn't really about responding to internal criticism. For the third one, I think it's really about what makes sense for the characters. When you are making an action movie, the action star is really an avatar for you to go through that situation. Its about the plot and action. This really isn't about the plot. It's about these guys going through some sort of horrendous growth experience. If we are going to end it...This isn't James Bond. We're not going to do The Hangover 20...There will be another one, and it will be the hangover to end all hangovers. And in a sense, it has to go to another level, again. The Hangover Part II goes to another level in terms of how dark and insane it gets. The Hangover Part III will go to another level for the guys."

None of this has been confirmed by Warner Bros., so we'll just have to wait and see how the story line of The Hangover Part III turns out.
