Paul Rudd, Jack Black, Jane Lynch, Danny Trejo, Ed Helms & More Reportedly Joining 'The Muppets'

Lady Gaga May Appear Alongside Rumors Of John Krasinski, Donald Glover & More

It's time to get things started is right. The cast to the new "The Muppets" movie -- spearheaded by star and superfan Jason Segel -- is expanding. We've already been promised several celebrity cameos and now Production Weekly have tweeted that myriad well-known actors have joined the growing ensemble. First and foremost is Paul Rudd who will evidently voice Walter The Muppet, the main new character (seen above with an iPhone) who stars alongside Segel and Amy Adams (Chris Cooper and Rashida Jones are already part of the cast).

Evidently many more are joining including Jack Black, Donald Glover, Jane Lynch, Danny Trejo, Zach Galifianakis -- who had been reported to be in negotiations a few weeks ago -- though it's unknown if their parts are those aforementioned celebrity cameos or actually a tangible part of the film's plot (our guess is the former). Apparently that's not all, and Prod Weekly is reporting ("hearing" which sounds just more like whispers) that Lady Gaga will be involved and that members of her entourage will include John Krasinski, Ed Helms and Eric Stonestreet (ABC's "Modern Family"). Will that entourage be muppets and will these rumored actors be providing voices or will they appear as themselves?

All of that is unknown, but most of this tweet report, if you want to call it that, seems to ring true. Rudd already co-starred with Jason Segel in the enjoyable "I Love You, Man" (as did Rashida Jones) and current pop culture touchstones like Jane Lynch from "Glee" and Gaga seem to be logical/the exact type of guest stars that would have appeared on "The Muppets" when it was on TV. Moreover, The Wrap, no doubt rushing to Sharon Waxman's rolodex when they saw the tweet, is confirming that Lynch and Trejo are indeed part of the cast, so at least some of this is true and we're sure it's only a Variety or Hollywood Reporter article away from hearing more confirmations.

Scripted by Segel and Nicholas Stoller ("Forgetting Sarah Marshall"), James Bobin (”Flight Of The Conchords”) will direct the film that is aiming to hit theaters on December 25, 2011. Production should be starting any day now if it hasn't already.
