Leymah Gbowee, the Liberian activist who won the Nobel Peace Prize this month, talks to Brian Lehrer about her work, as well as her film, Pray the Devil Back to Hell. The title of the film is a play on warlord Charles Taylor's use of religion to support his crimes against humanity. In the interview, Gbowee talks about the truly brave methods she and the women she organized used to bring peace to Liberia during its second civil war (including a sex strike). Listen to the full interview below. You can watch the film tonight on PBS at 10pm EST, or stream it live here.
