George Clooney never uses a body double, but his “Up in the Air” co-star Vera Farmiga (pictured) did for a shot that showed her fully nude from behind. She had recently given birth. “The breast milk down both sides — it would have been inappropriate,” she tells Entertainment Weekly. Clooney plays a rootless bachelor who seduces Farmiga’s character in an airport, and educates a naive co-worker played by Anna Kendrick. Clooney told the magazine the role suited his ladies’ man reputation. “I’m not completely unaware of people’s perceptions of me. I sort of felt like, if you were ever going to deal with it, this is probably the best way to do it.”
