The Muppet Mindset by Ryan Dosier
The Muppet Mindset 
This one kills me, but a few months ago Eric Stonestreet confirmed on his twitter that he was NOT in the film and was sorry to say it.
I just read that Katy Perry may be in this, true or not true?
Jack Black actually is in one of the trailers. He's the one with the bowling ball on his head that Gonzo is trying to knock off.
Bowling pin I mean. Sorry.
Reports from a screening at the Savannah Film Fest mentioned cameo(s) from The Big Bang Theory. As a two time Emmy winner from that show, Jim Parsons should be put in the pretty much confirmed category.
