Courtesy of Sundance Film Festival Mark Cousins' 'The Story of Looking' will close the June event, which will mix both online and physical screenings as the U.K. continues to come out of the COVID-19 lockdown. The U.K.'s biggest documentary event, Sheffield Doc/Fest, has announced the opening and closing films for its 2021 edition, which — like 2020 — will mix both online and physical screenings due to COVID-19 restrictions. Summer of Soul, the celebrated feature debut of Ahmir "Questlove" Thompson about the little-known 1969 Harlem Cultural Festival, is getting its European premiere to open the festival on June 4, and, according to organizers, "inspire the next 10 days of programme through its testimony of a unique moment in history" and the "transformative power" of culture and music.
