We were unable to preview Banished before the publication of this feature, but the subject of Marco Williams's documentary, a nominee for the Grand Jury Prize at the last Sundance Film Festival, is thought-provoking. The film allows the director to explore the legacy of slavery in small towns in Georgia, Missouri and Arkansas, where African American families were violently thrown out of their homes by their white neighbors in the years between the Civil War and the Great Depression. Banished will play once on Thursday, June 21 at the Human Rights Watch International Film Festival before returning to New York City on October 10 at Film Forum.  Ed Gonzalez
