Performances Ralph Fiennes anchors the film with a measured, quietly commanding performance as Lawrence—an observer forced into active moral arbitration. Stanley Tucci provides warmth and political savvy as Bellini; John Lithgow brings gravitas to Tremblay; Sergio Castellitto embodies doctrinal fervor as Tedesco; Isabella Rossellini’s Sister Agnes is an incisive, memorable presence. The ensemble work is frequently singled out in reviews for creating an authentic international College of Cardinals.
