After two years of virtual editions, the Sundance Film Festival is returning to Park City, Utah, armed with a robust slate of diverse features and documentaries that will premiere over 10 days beginning on Thursday. There are documentaries about the war in Ukraine with “20 Days in Mariupol,” as well as stories about women in Iran, transgender people and film about indigenous communities, women’s rights and sexuality, Alzheimer’s, ableism and an unpunished war crime. Festivalgoers will see some unexpected turns from stars, like Jonathan Majors, Daisy Ridley, Anne Hathaway and Phoebe Dyvenor. And, as always, there are intimate portraits of famous faces, like Michael J. Fox, Stephen Curry, Judy Blume Brooke Shields.
