Blow Up (1966, Michelangelo Antonioni)
Filled with silences, long-takes, and metaphysical gestures, Antonioni’s only box-office hit is a must see that demands erudition and serious contemplation. David Hemmings plays a vapid, nihilistic, and disaffected fashion photographer who discovers a startling secret when he blows up a series of his photographs. In describing the movie, you can use words like “alienation.” It is based on a short story of the same name by Julio Cortázar, an author who smart people read. The final scene, a mimed tennis match, goes down as one of the best in cinema history.
