When we speculated that the new Muppet movie was missing only a Paul Rudd, Seth Rogen, or Will Ferrell cameo to be considered complete, we omitted another name from that general comedy arena, Zach Galifianakis, whom we just assumed would be way too busy, considering he’s doing just about everything these days under his recently assumed mantle of Most Powerful Man In Hollywood. But during a video interview with E! Online, Galifianakis’ Due Date co-star Robert Downey Jr. revealed that Galif… You know what? We’re just going to say G. from now on. He revealed, even though he apparently wasn’t supposed to yet, that G. will be dropping by the Muppets set for a couple of days to do a cameo. This, despite the fact that Sam The Eagle has made several openly bigoted remarks toward weirdoes.
