In a major get for the two-year-old IU Cinema, “the most important film director alive” (Truffaut, back when he was) presides over an extensive retrospective and gives two lectures. Sept. 8: Fata Morgana (1971), a woozy head-trip in the Sahara. Sept. 9: Land of Silence and Darkness (1971), a documentary profile of a deaf-blind person. Sept. 10: Aguirre, Wrath of God (1972), a trip down the Amazon with Klaus Kinski as a Spanish conquistador and a large cast of rats, playing themselves. Sept. 11: In Search of Ecstatic Truth, a lecture by Herzog. Sept. 12: Fitzcarraldo (1982), in which a Kinski-played baron/adventurer — and Herzog as director, by exceedingly literal extension — attempts to push a boat over a hill. Sept. 13: The Transformative Role of Music in Film, a lecture by Herzog. Sept. 14: Bad Lieutenant: The Port of New Orleans (2009), an odd, belated sequel to Ferrara's 1992 film about a naughty cop, starring Nicolas Cage at his most unhinged; Grizzly Man (2005), a documentary portrait of a man who loved bears a bit too much; Nosferatu The Vampyr (1979), Herzog's consistently creepy remake of Murnau's silent classic; a public interview with Herzog by Professor Greg Waller. Sept. 16: The Enigma of Kaspar Hauser (1974), the 1975 Grand Jury Prizewinner at Cannes; Into the Abyss (2011), his most recent film, a documentary about the death penalty.
