PARK CITY, Utah (AP) - Anita Hill made national headlines in 1991 when she testified that then-Supreme Court nominee Clarence Thomas had sexually harassed her. At the time, "sexual harassment" wasn't part of popular vernacular. Hill was verbally attacked, and Thomas was confirmed. 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. Hill and Mock said Friday they made the film to educate and inform a new generation of Americans, to reflect the progress that's been made and to inspire continued conversation and efforts toward social and political equality. Hill said the film doesn't just look back, it looks forward, which allows viewers to reshape their thoughts on sexual-harassment issues.
