Conservative talk radio host (and proud, card-carrying blowhard) Rush Limbaugh is either an actor's best dream or worst nightmare. For the comparatively slim John Cusack (who once called the Bush administration "depressing, corrupt, unlawful and tragically absurd") it may be a bit of both. He and director Betty Thomas are wrapping up the script on a biopic, Rush, which they hope to start shooting sometime next year. Limbaugh has lead a colorful life, what with the Viagra-popping, the prescription drug fraud, and the shouting of "slut" and "prostitute" at law school students. We're sure it'll look even more glamorous on the big screen.
