In this undated photo released on Friday, Oct. 5, 2012 by Busan International Film Festival, South Korean director Chung Ji-young looks at a monitor for his movie "National Security" in South Korea. The film based on the memoir of a democracy activist who was tortured in the 1980s by South Korea's military rulers is provoking discussion about the country's not-so-distant authoritative past and the influence it will have on this year's presidential election.
