 Presentations of this film on television (broadcast, cable or home  video) required preservation of the widescreen format. This  presented a problem in the U.S. since certain F.C.C. technical  regulations did not permit a portion of the screen to be left blank  as in letterboxing. The problem was solved by making the area above  and below the frame gray. The regulations have since been changed  and letterboxing with black borders is now permitted.
