 Within the huge spaces of the sets they employed unusually active movements for the camera whose virtuosity makes them highly visible to the spectator.At Saccard's party the camera glides back and forth above the guests; in the bank scenes it moves alongside and among the crowds.Most strikingly of all, in the scenes at the Bourse, a vertical shot from the high ceiling down to the "corbeille" (dealers' enclosure) makes the scene resemble the teeming activity of ants; and an automatic camera then creates a dizzying effect as it spirals down towards the floor.
