Michelangelo Antonioni directed some of the most influential films of the sixties and early seventies, including "Blowup", “L’Avventura” (1960), “L’Eclisse” (1962), and "La Notte" (1961), the last three of which put him on the international map as a cerebral filmaker who excelled at exploring how humans have become alienated from each other in our modern world.
How influential was Antonioni? Oh sure, I could go into the "Silver Spoons" episode where Ricky takes his date to see "Blowup" and they both spend a couple of minutes (and that's valuable sitcom minutes we're talking here) discussing the movie. But I won't.
Instead, why don't you take a gander at the New York Times obit here.
