A and B in Ontario -- Film Description:
"A & B in Ontario was completed eighteen years after the original material was shot. After [Hollis] Frampton's death, the film was assembled by [Joyce] Wieland into a cinematic dialogue in which the collaborators (in the spirit of the sixties) shoot each other with cameras."
