John Cusak - a staunch and outspoken liberal - is to produce and star in Rush, the working title for a film that tells the story of conservative radio host Rush Limbaugh, Fox reports. 

Betty Thomas, the Hollywood director in charge, has confirmed, alongside Cusack's production company, that the Con Air star will feature in the film, as well as fulfilling a production role. She also confirmed that production would start early next year. Limbaugh paints a controversial figure in the world of politics and current affairs; earlier this year, he called a Georgetown law student a "slut" and a "prostitute" on air for arguing to Democrats in Congress that health plans should pay for contraception. And just this week, he poked fun at Republican New Jersey Gov. Chris Christie for his "bromance" with Obama after Christie praised the president's response to the aftermath of Hurricane Sandy.

It will be interesting to see how Cusack depicts the larger than life character of Limbaugh; not only are they poles apart morally and politically, they couldn't differ more physically. Cusack cuts a slim figure with dark features, while Limbaugh sports a paunch and is balding. There is no confirmation, however, that Cusack will indeed perform the main role, as his production company offered no other information on the matter.
