Officially the capital of Germany again, though many are questioning the wisdom of moving the government back there, Berlin became the nation’s cinematic capital during the ’80s, as the Munich-centered New German Cinema fragmented and its principal survivor, Wim Wenders, moved there to contemplate angels over the Wall. A series of seven films set amid the city’s tumultuous recent history, “Berlin Blues” includes City of the Lost Souls (Oct. 27), by gay sexual liberationist Rosa von Praunheim; Drachenfutter (translated literally as Dragon Chow but released in Britain as Spicy Rice; Nov. 17), documentarian Jan Schütte’s first fiction film, about a Pakistani and a Chinese immigrant attempting to make a new life in Hamburg (well, right country, anyway); and Christiane F. (Dec. 8), a controversial 1981 semi-documentary portrait of a 13-year-old junkie and her circle (with music by part-time Berliner David Bowie). The films are shown Wednesdays at 6:30 p.m. through Dec. 15 at the Goethe-Institut, 1607 New Hampshire Ave. NW. FREE. (202) 319-0702. (Mark Jenkins)
