Deadline.com says the film is in early stages, but Cusack and director Betty Thomas are both interested.
The as-yet-untitled Limbaugh biopic would be non-partisan. "The script would explore the rise and reinvention of American talk radio, and Limbaugh's continued influence and impact over the last three decades in that world," said a spokesman for Cusack’s production company, True Crimes Productions.
Former “Hill Street Blues” star Thomas also helmed “Private Parts,” the film about "shock jock" Howard Stern, who starred as himself.
Actor John Cusack is reportedly considering a biopic on ultra-conservative radio show host Rush Limbaugh.
