'The Hangover 3': Zach Galifianakis Reveals Mental Patient Details Of Proposed Third Film

Before they could even cash the checks from the gigantic opening weekend, Warner Brothers, the studio behind the $350+ million and growing raunchfest "The Hangover: Part II," signed off on and got the wheels in motion for another sequel.

Given the weak reviews for the second film, director Todd Phillips said that any third film would differ substantially from the first two, which both involved putting the pieces back together after an epic blackout bachelor party and trying to find a lost companion. In his new cover story for Rolling Stone, star Zach Galifianakis confirmed a new plot that would certainly be a significant change.

"They want to do a Hangover III. I'm getting fricking phone calls already," he said. The plot, the story reveals, would involve his character, the mentally unstable man-child Alan, being sprung loose from a mental institution by his fellow Wolf Pack buddies, played by Bradley Cooper, Ed Helms and (maybe) Justin Bartha.

That'll mean even more big press for the exploding star, who spent years as an avant garde comedian and struggling actor. But for all the big money and spotlight he's receiving, he's not exactly pumped for the change.

“I’ll be honest with you: I’m not adjusting to it well. I don’t mean that as a complaint. Most people wouldn’t be well-adjusted. I just get confused by people asking me questions," he told the magazine. "For years, nobody asked me a question, ever. So now when someone says, ‘Oh, you’re going to be on the cover of Rolling Stone,’ my first reaction is, ‘Ehhh, I don’t think that’s a good idea. I mean, it’s cool – but does it have to be the cover? What’s Blink-182 doing these days?’”

He's also not crazy about the admiration of other celebrities. Including certain pop stars.

“I saw that Ke$ha woman the other day,” he told the magazine, recalling a story about getting an email from her inviting him out to get a drink. “She was sitting by herself, and I walked up to her and said, ‘Listen, I got your e-mail. Your music is really bad! I don’t know who listens to it, but I imagine it’s, like, six-year-olds – and it’s a bad message.’”

Then again, maybe he was upset about something she told Sirius satellite radio a few months before.

"I want to make out with the fat guy from 'The Hangover' …He's amazing. I like big, fat guys with beards that wear thick glasses," she told the network's "The Morning Mash Up" show in late January.
