John Cusack, whose new film "War, Inc" is in theaters and whose MoveOn.org ad is tearing up the airwaves, was the #1 story on "Countdown" Friday night when he sat for an interview. Cusack and Olbermann talked about politics, celebrities getting involved with politics, war profiteering and more. Why do the ad? "If torture is going to be a profit business... I think your conscience dictates you speak out."
