“On Her Shoulders” is Alexandria Bombach’s deeply moving portrait of Yazidi genocide survivor-turned-global advocate Nadia Murad. Winner of the Sundance Film Festival’s U.S. Documentary Directing Award and the prize for Best Documentary at the recent Camden Film Festival, the film focuses on Nadia’s life as the 23-year-old participates in a dizzying display of diplomacy—from giving testimony before the U.N. to visiting refugee camps to soul-bearing media interviews and one-on-one meetings with top government officials. In Friday’s “Leonard Lopate at Large,” Alexandria and co-producer Elizabeth Schaeffer Brown discuss this important film and the inspiring woman it profiles.
