"Blank City" may seem alien to viewers who don't have an affinity with punk culture, but this documentary is an engrossing look at the late-'70s, underground cinema that rose alongside New York's No Wave/CBGB's musical movements. Building on Andy Warhol's "Everybody is a director, everybody is a star" ethic, a clique of rebellious street characters grabbed Super 8 cameras and began making movies. The results were raw, amateurish and often controversial, but had a refreshing directness and lack of artifice. Few of the discussed works are well-known or readily available today (prime exceptions: Susan Seidelman's "Smithereens" and Jim Jarmusch's "Stranger Than Paradise"), so "Blank City" is bound to include fresh information for even hardcore film buffs. Filmmakers like Richard Kern, Eric Mitchell, Amos Poe, Beth B, Nick Zedd, Charlie Ahearn and Vivienne Dick are featured, and participating actors such as Steve Buscemi, Deborah Harry, Lydia Lunch and John Lurie are interviewed. Thurston Moore (inevitably), James Chance, Ann Magnuson, Jim "Foetus" Thirlwell and John Waters add further soundbites.
