Why 'Game Change' Chose Julianne Moore Over Tina Fey for Sarah Palin

Moore earned raves for her work as the under-fire candidate, from the makeup-assisted physical transformation to her assumption of Palin's Alaskan-by-way-of-Idaho accent (aided by an iPod full of speeches).

Need proof? While the movie is now available on demand on HBO, a patient YouTube user has also put together a mashup of the two women, comparing their same speeches and conversations to show just how close Moore got to getting Palin down cold.

Between the uncanny resemblance and the dialogue sparked by the film, Game Change served its ultimate purpose: bringing in eyeballs; its premiere on Saturday night brought in 2.1 million viewers, while 3.6 million took in its four weekend screenings altogether, making it the most-watched HBO Original Film in eight years.
