"The films of Gunvor Nelson compose one of the great bodies of independent work in the history of the medium,” wrote scholar and curator Steve Anker. Former San Franciscan Nelson returns to the Bay Area from her native Sweden this November to present her recent digital work and a selection of her earlier films. San Francisco Cinematheque presents an additional program on Sunday, November 12, at Yerba Buena Center for the Arts. Information: www.sfcinematheque.org.
