Most of these 15 films by nine filmmakers (screening over two nights) are well worth seeing, especially those by Andy Warhol and Warren Sonbert. In Warhol's Kitchen (1965, 66 min.), a static camera observes characters in a kitchen sitting, talking, and playing at seduction. Warhol's passive-aggressive view of his emotionally vacant characters is heightened by the blocklike black-and-white composition, which imbues the refrigerator with as much presence as the cast (in fact, the furniture is included in the credits). It's screening Friday night as part of a 133-minute program that includes Tony Conrad's The Flicker (1966) and Ken Jacobs's Blonde Cobra (1963). Most of Warren Sonbert's films are multivalent, sometimes humorous montages of lush images from around the world, edited to both reinforce and undercut one another: marathoners crossing New York's majestic Verrazano Narrows Bridge in Noblesse Oblige (1981, 25 min.) are followed by scenes of the raising of a Chicago River drawbridge. It screens along with three other Sonbert films as part of a 150-minute program that includes works by Peter Kubelka, Willard Maas, John Hawkins, Marie Menken, and Christopher Maclaine.
