The High Fidelity star will portray the political commentator in Rush, which will begin shooting next year (13).

28 Days filmmaker Betty Thomas has already signed on to direct and the project will be developed by Cusack's production company New Crime Productions, reports the New York Times.

The casting decision is set to raise a few eyebrows - the actor bares little physical similarity to the heavy-set 61 year old, and Cusack has long been an outspoken liberal.
