Ver Cuevana 3. An educational physics film utilizing a fascinating set consisting of a rotating table and furniture occupying surprisingly unpredictable spots within the viewing area, Leacock’s Frames of Reference (1960), features fine cinematography by Abraham Morochnik, and funny narration by University of Toronto professors Donald Ivey and Patterson Hume, in a wonderful example of the fun a creative team of filmmakers can have with a subject other, less imaginative types might find pedestrian.
