“The most important question – Where is the experimental film movement? – is the one which I wish someone could answer for me”, wrote Maya Deren in August 1946 to the filmmaker Frank Stauffacher who was preparing a program for the San Francisco Museum of Art called “Art in Cinema”. Deren, who was 29 at the time, was a reference because in 1943 she had already started showing the experimental films she made with Alexander Hammid to a select audience.
