 Just as the chimney begins to fall apart, the shot is broken off and the entire movie follows, after which the shot of the chimney is resumed at the point it left off, showing its disintegration in mid-air, and closing the film with its collapse on the ground.A similar interrupted continuity is employed in this quartet's starting with a cadenza for cello alone that is continued by the first violin alone at the very end.On one level, I interpret Cocteau's idea (and my own) as establishing the difference between external time (measured by the falling chimney, or the cadenza) and internal dream time (the main body of the work)—the dream time lasting but a moment of external time, but from the dreamer's point of view, a long stretch.
