DIRECTOR'S PREVIEW of $50,000 slave market set - one of 39 used in The Robe. Smooth picture action which makes for greater screen realism is plotted here.

CINEMASCOPE SCREEN is curved, but not as much as Cinerama's. Purpose is to maintain sharp focus throughout the width of the picture. Because  screen size  is greatly  increased,  its  surface  is  mirrorized   with 

millions of tiny lenses to reflect more light. Cinemascope's three loudspeakers duplicate positions of recording microphones.
