ABC is finally taking the wraps off its 9/11 commission report miniseries, choosing Harvey Keitel to star and David L. Cunningham (“To End All Wars”) to direct the Marc Platt-produced project. Shooting has begun in Toronto for what’s expected to be a three-month shoot for the as-yet untitled six-hour miniseries, which is budgeted at $30 million-$40 million. Keitel will play FBI agent John O’Neill, a passionate anti-terror fighter who was the leading expert on Al Qaeda at the time of the 9/11 attacks. He perished when the first airplane hit the World Trade Center. Other casting includes Patricia Heaton as the U.S. ambassador to Yemen, who clashed with O’Neill; Amy Madigan (“Carnivale”) as a top CIA analyst; Shaun Toub (“Crash”) as the FBI informant who helped bring down the “blind sheikh” behind the first WTC attack; and Stephen Root (“NewsRadio”) as White House terrorism guru Richard Clarke.
