The Museum of Fine Arts, Boston Film Program and the Harvard Film Archive will present a retrospective of the films of Louis Malle from September 1-October 4. This chance to see the great French director’s best-loved works on the big screen features new prints of seven well-known classics, which run the gamut from romance and intrigue ("Elevator to the Gallows," "The Lovers") to youthful escapades ("Zazie in the Metro," "Murmur in the Heart") to the Nazi occupation ("Lacombe," "Lucien" and "Au revoir les enfants," both co-presented by The Boston Jewish Film Festival).
