Though he is perhaps best known for his virtuosic performances in ads for sparkling wine and frozen peas, Orson Welles once made movies. At 25, he cowrote, directed, produced, and starred in his feature debut, Citizen Kane, a masterpiece that routinely ranks among the greatest films ever made. His follow-up, The Magnificent Ambersons, is fantastic as well, despite being butchered irreparably by RKO Studios before its release in 1942, and features prime examples of Welles’s distinctive camerawork. Today’s back-to-back 35 mm presentations of these films (starting with Ambersons) is a rare opportunity that should not be missed.
