So the astonishing physical resemblance Julianne Moore showed in her latest role as Sarah Palin is only skin deep.
HBO has released the trailer from the film Game Change, showing the Hollywood red-head playing the right-wing politician.
The project is an adaptation of the best-selling book of the same name, which centres around the power politics of 2008's US presidential campaign.
The drama also features Ed Harris as John McCain and Woody Harrelson as his legal advisor, Steve Schmidt.
