It's Halloween 2008 all over again and Julianne Moore is getting in on the fun.

Here we see Moore going rogue as former Republican vice presidential candidate Sarah Palin for the HBO film, Game Change. In the film, Moore's Palin is joined by Ed Harris as John McCain, Woody Harrelson as Steve Schmidt, Melissa Farman as Bristol, and Ron Livingston as senior adviser Mark Wallace. Production begins today with director Jay Roach, but this first photo should be enough to keep Tracy Morgan going until there is a trailer.
