Julianne Moore fully immersed herself in character while preparing for her upcoming role.
The 51-year-old Oscar-nominated actress portrays American politician and 2008 vice presidential candidate Sarah Palin in HBO's political drama Going Rogue.
The film based on the eponymous book by John Heilemann and Mark Halperin follows the 2008 US presidential election in which Senator John McCain invited Sarah to be his running mate against Barack Obama.
Julianne went all out to authentically depict the politician.
"I listened to her book on tape, Going Rogue, I went on YouTube and found all of her media appearances, all the speeches, debates, the convention speeches, and put them all on my iPod," Julianna explained to host Jay Leno on his American late-night TV talk programme The Tonight Show Thursday. "I wiped everything off except for [Vanilla Ice's 1990s track] Ice Ice Baby, which is the song that my daughter ice-skated to."
Julianne's two children were mortified by the sounds emanating from their mother's iPod.
"My 14-year-old son was really embarrassed by that," Julianne laughed. "There is nothing worse than a mum who has nothing but Sarah Palin and Ice Ice Baby on her iPod. I'd put it on in the car, I'd listen to it when I was running. I'd listen to it constantly. It was really a total immersion."
Julianne altered her physical appearance drastically for this film.
"Everything had to change - my skin tone, the shape of my face, my lips, my eyes, I wore contact lenses," Julianne shared. "Everything was completely changed."
Sarah Palin's current and former aides have lashed out against the movie, complaining that Julianne's portrayal is nothing more than caricature.
Julianne refutes this assumption, as the actress feels the film comments on broader American issues.
"It's about the campaign. It's also about how we elect our leader," Julianne said. "It's more of a portrait of this particular time in history, of this particular campaign, than it is about Sarah Palin."
Going Rogue starring Julianne, Woody Harrelson and Ed Harris premieres on HBO in America on March 10.
