“DAMNED” GOOD IDEA:The Brooklyn Academy of Music has an early Christmas gift for film lovers: a retrospective tribute to Luchino Visconti (1906-1976), the Milan aristocrat who became one of Italy’s – and the world’s – greatest film makers. His best-known work, “The Leopard” (1963), has al ready screened at BAM, but there’s lots more to come be fore the festival ends Dec. 16. Tomorrow and Sunday, for example, is “The Damned” (1969), Visconti’s take on the rise of the Nazis as seen through a German munitions family. With Dirk Bogarde, Charlotte Rampling and Helmut Berger, who dons drag for a mean impersonation of Marlene Diet rich. All the films unreel at BAM Rose Cinemas, Lafayette Avenue, off Flatbush Avenue, in Brooklyn; http://www.bam.org.
