Sundance is going virtual this year, a gift to viewers around the world, who can now watch premieres at the click of a button. Among the more than 70 screenings taking place over the week-long festival are documentaries on life in North Philadelphia (Dear Philadelphia, January 28), a mission to save kidnapped Yazidi women and children (Sabaya, January 30), and the fight between a group of nonconformist feminist nuns and a powerful patriarchy (Rebel Hearts, January 29). A biopic about William O’Neal, an FBI informant who infiltrated the Black Panthers to take down Fred Hampton, stars Lakeith Stanfield and Daniel Kaluuya (Judas and the Black Messiah, February 1). Nearly half of the films are directed by women, including Lucy Walker’s documentary on the Northern California wildfires (Bring Your Own Brigade, January 30), Mariem Pérez Riera’s Rita Moreno: Just a Girl Who Decided to Go For It (January 29), and debuts by Robin Wright (Land, January 31) and Rebecca Hall (Passing, January 30, based on Nella Larson’s Harlem Renaissance novel, and starring Tessa Thompson and Ruth Negga). —J.V.
