However, when MTV News caught up with Rudd recently, the star crushed the collective dreams of Judd Apatow acolytes everywhere, explaining that a cameo alongside Kermit's crew is just not in the cards right now.
"I wish that I was. It's all rumor," Rudd confided at the Gotham Awards last week. "I wanted to be in it, and I talked to Jason but I think there was some things that happened and I don't know if I'm gonna get to do it."
As many would be, he's totally torn up about missing out on the Muppet-fest.
"It blows actually," he pouted playfully. "It really sucks."
Up next, fans can catch Rudd alongside Jennifer Aniston as a broke couple that decide to take up residence at a commune in the Apatow-helmed "Wanderlust." But after that, Rudd quipped that he wanted another crack at the Muppet franchise, and even came up with a few inspired titles for a sequel to Segel's project.
"I'm hoping for the 'Muppet Movie 2.' I'm playing Charles Grodin in 'Muppet 2: Electric Waterloo?' Beaker-loo?" he joked, before offering a truly game-changing suggestion: "Muppet Movie 2: The Muppets Are Still Taking Manhattan."
Even with Rudd officially out the mix, the confirmed lineup of guest starsshould pack the film with plenty of laughs. Jack Black, Zach Galifianakis, Billy Crystal and Alan Arkin are all slated to appear in the project.
