'Muppets' Movie Adds Jack Black, Zach Galifianakis, Billy Crystal And Jean-Claude Van Damme Cameos

Zach Galifianakis Muppets movieWhen MTV spoke to Zach Galifianakis at the "Due Date" premiere earlier this month, the funnyman wouldn't deny outright that he's going to be in James Bobin's new "Muppets" movie. And now a new report from The Hollywood Reporter's Heat Vision blog claims that Galifianakis is playing a hobo alongside a legion of other celebrity cameos in the upcoming "Muppets" flick.

We already knew that Amy Adams, Chris Cooper and Rashida Jones would be joining Jason Segel in significant roles. It looked like Jane Lynch might have a cameo, but she's since shot down those reports. Not to worry, a fresh new crop of celebs are joining Galifianakis in cameos.. Alan Arkin has been fingered as a tour guide, Jack Black will play a kidnapping victim, and Billy Crystal and Jean-Claude Van Damme are also showing up in unspecified cameos.

Indeed, the film's star-studded guest list is already long and distinguished, and might even have been longer/more distinguished had scheduling conflicts not prevented others from signing on. The film is currently shooting in Los Angeles, though, so don't be surprised if it manages to rope in a few more surprise participants off the street before production wraps.

It's hard to deny that Galifianakis will likely make a striking hobo, assuming this bit of casting intel proves true. Past "Muppets" productions have gorged on cameos, and it's great to see that trend is still alive and well. That Lady Gaga rumor should be worth keeping tabs on, and with Jim Henson's characters teaming up with a new generation of Hollywood talent, as well as veterans like Billy Crystal, you have to wonder how big the cameo tent can get.
