MacArthur Fellow Stanley Nelson has devoted his career to documentary explorations of the African American experience. The 65-year-old director/producer has made films on Marcus Garvey, the Freedom Riders and the Black Panthers. His most recent film is Tell Them We Are Rising: The Story of Black Colleges and Universities, which premiered this week at the 2017 Sundance Film Festival. Nelson hired editor Kim Miille to cut the film. Below, Miille shares her thoughts on historically black colleges and universities (HBCUs), making archival photos and letters cinematic and her origins as an editor.
