Sarah Palin, is that you? We have to admit, Julianne Moore made us do a double take in this new promotional photo for the upcoming HBO film Game Change ... in which the 50-year-old actress plays the former Alaska governor.

The movie, which starts production next week, also stars Ed Harris as John McCain and Woody Harrelson as McCain's senior advisor Steve Schmidt.

Can't wait to see Julianne play the 47-year-old politician. Love that Palin hairdo!
