Commonweal film critic Richard Alleva has been fascinated with Graham Greene since childhood; he explores why loyalty and betrayal are recurring themes in Greene’s work. Mary Frances Coady, author of Merton & Waugh: A Monk, A Crusty Old Man & The Seven Storey Mountain, discusses Waugh’s and Merton’s longtime correspondence and why the friendship ultimately petered out.

A restored version of the 1949 film noir, The Third Man, based on a novel by Graham Greene, who also wrote the screenplay, stars Orson Welles and was directed by Carol Reed. It is is showing at Cinestudio, the theater at Trinity College in Hartford, through Thursday, 8-6-15.
