What is Casting Couch? A list of the weekend’s casting news, headed up by various Guardians of the Galaxy castings, but also including news on what’s up with Judd Nelson. The cast of Marvel’s space adventure, Guardians of the Galaxy, is getting so extensive, and so many actors appearing in it have been described as having a “lead role,” that it’s starting to get pretty confusing as to how all this stuff is going to fit into one movie. We’ve got intergalactic superheroes, intergalactic police, bounty hunters, liaisons to government agencies on Earth, and who knows how many other players introduced at this point. Nonetheless, Heat Vision has a report that the film has now cast its “lead female villain,” and the lady they’ve got to play the role is Doctor Who’s beloved companion, Karen Gillan. As if this balls crazy movie didn’t have enough geek cred already.
