Italian screenwriter, playwright, novelist, journalist, and drama critic who was especially noted for his social satires. He became a leading figure of the Italian motion-picture industry after World War II, collaborating with writer Tullio Pinelli on the early films of writer and director Federico Fellini (Fellini, Federico).

Trained as an architect, Flaiano started a career in journalism, contributing critical essays to the magazines Oggi, L'europeo, Mondo, and L'espresso. His first play, La guerra spiegata ai poveri (1946; “War Explained to the Poor”), displays his sharp, subtle humour. His first novel, Tempo di uccidere (1947; A Time to Kill), won him the Strega Prize in 1947. He began writing film scripts during World War II and infused a sense of realism into such Fellini films as La strada (1954; “The Road”), La dolce vita (1960; “The Sweet Life”), and Otto e mezzo (1963; 8¹/₂).

Flaiano's other books include the short-story collections Diario notturno (1956; “Night Journal”) and Una e una notte (1959; “One and One Night”), as well as the play La conversazione continuamente interrotta (1972; “A Continually Interrupted Conversation”).
