Well, this bit of casting news is coming out of left field from the Hollywood Reporter. Executive producer, Joel Surnow, who jokingly describes himself as a "right wing nut job" has hired on actress/outspoken liberal, Janeane Garofalo, to star in the coming season of 24. She will be playing a government agent sent to investigate the crisis befalling Jack Bauer and company. She joins the only other new casting, Cherry Jones (Signs), who was tapped to play the new U.S President.
The show itself hasn't began production yet due to 2 delays. First delay was caused by Fox nixing an "Set in Africa" storyline and the 2nd delay was Imagine Entertainment demanding to have the full season of scripts done before one scene is shot. Production will begin September 10.
