Anita Hill poses for a portrait during the Sundance Film Festival on Friday, Jan. 18, 2013, in Park City, Utah. Hill made national headlines in 1991 when she testified that then-Supreme Court nominee Clarence Thomas had sexually harassed her. Now, more than 20 years later, director Freida Mock explores Hill's landmark testimony and the resulting social and political changes in the documentary "Anita," premiering Saturday at the Sundance Film Festival.
