She was nominated this year for a BAFTA and Golden Globe Award for her performance playing a lesbian matriarch in The Kids Are All Right.
But Julianne Moore is set to take on a very different role - that of vice presidential candidate and Alaskan governor Sarah Palin.
The 50-year-old four time Oscar nominee has signed on to play the presidential running mate in a TV adaptation of the best-selling book Game Change for HBO.
According to Entertainment Weekly, Game Change will be directed by Jay Roach -- who directed Meet The Parents, and written by Danny Strong, who previously teamed up for HBO's docudrama Recount, which focused on the aftermath of the 2000 election.
The film will follow the 2008 presidential campaign between John McCain and Barack Obama.
No other cast members have been announced but with Jay Roach attached to the project it is likely to be an all-star cast.
Julianne has recently gained praise for her award-winning film The Kids Are All Right.
The film was nominated for best picture at the Oscars while her co-stars Mark Ruffalo and Annette Bening were up for best supporting actor and best actress respectively.
Moore says the film, which focuses on a lesbian couple raising two children, made her reflect on her own family values.

Await: New mobile battery with power lasting months
A flat battery on your mobile phone can leave you in a sticky situation, but new research could mean you might go months without charging it.
A team of electrical and computer engineers at an Illinois university may have solved the problem by using 'nanotubes' - carbon tubes 10,000 times smaller than a human hair.
The scientists replaced the metal wiring in mobile devices' batteries with the nanotubes and believe the changes could extend battery life by up to 100 times.
'I think anyone who is dealing with a lot of chargers and plugging things in every night can relate to wanting a cell phone or laptop whose batteries can last for weeks or months,' said Eric Pop of the Beckman Institute for Advanced Science and Technology.
Mr Pop claims his team's research could one day mean a mobile device like an iPhone could see hugely extended battery life, possibly to the point that it could run by harvesting thermal or solar energy rather than relying on a battery.
The research could also prove groundbreaking for devices much larger than mobile phones or portable computers.
'We're not just talking about lightening our pockets or purses,' Mr Pop explained.
'This is also important for anything that has to operate on a battery, such as satellites, telecommunications equipment in remote locations, or any number of scientific and military applications.'
The scientists believe their latest study is just the beginning for improving battery life and hope to make devices' power consumption 1,000 times more efficient.
The findings, published in a report in the Science journal, come in the same week that Google admitted up to 260,000 smartphones had been hacked after handset users unwittingly downloaded virus-infected apps.
The threat came to light last week when the technology giant was forced to withdraw at least 50 apps from its official Android Market.
