Diagonal(1973)

movie - first aired/released 1973-09-05

Directed by William Raban

Three screen piece. "I was looking for a pure image, an image which was intrinsic to the medium of film. This film is not an abstract film; the subject is the projector gate, the plane where the film frame is arrested in the projected light beam, and the frame whose edges contain and divide the projected illusion from the blacked-out present of the movie theatre.
