The papal thriller “Conclave” won best ensemble at the 31st Screen Actors Guild Awards, a surprise twist that added one final wrinkle in an unusually unpredictable awards season. In winning the guild’s top award Sunday, Edward Berger’s Vatican-set drama triumphed just as the Catholic Church was praying for the health of Pope Francis. Timothée Chalamet won best male actor, upsetting Adrien Brody and putting the 29-year-old on course to possibly win his first Oscar. Demi Moore won best actress.
