Director: Ernie Gehr
Year: 1970
Synopsis: "A literal 'Shock Corridor' wherein Gehr creates a stunning head-on motion by systematically shifting focal lengths on a static zoom lens as it stares down the center of an empty, modernistic hallway. (From Canyon Cinema)
Director: Hollis Frampton
Year: 1970
Synopsis: "Frampton's film is an exercise in mathematical logic in cinema. Or is it a mechanical logic?... It's about alphabet. It's about the unities of similarities. It's about sameness in a confusion. (Jonas Mekas, Village Voice via Filmmakers' Co-op.)
