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.

Albert Einstein's theory of general relativity has revolutionised our understanding of gravity, space and time. Initially acclaimed, then forgotten, and now rediscovered, the adventure of this hundred-year-old theory has marked the scientific history of the 20th century. From its inception, a mathematical difficulty arose that could have nipped the theory in the bud: the Schwarzschild singularity. In the company of great international relativistic physicists, the viewer embarks on a discovery of this theory with a singular destiny. We discover a "curved" universe that proves to be even stranger than Einstein had envisioned, and harbours some objects - such as black holes - that still challenge today's scientists.
