This year’s Virginia Film Festival will include the national premiere of the documentary “Charlottesville,” which will be followed by an address by Martin Luther King III. After his address, King, son of the Rev. Dr. Martin Luther King Jr., will take part in a conversation moderated by Larry J. Sabato, director of the University of Virginia’s Center for Politics. King’s event is being presented as part of a partnership with the UVa Center for Politics, Community Idea Stations and the Frank D. Batten School of Leadership and Public Policy.
