Filmed in two different versions: one in CinemaScope (2:55) and one in a "flat" widescreen (1.77). The CinemaScope version is the one generally screened, but both are available. The main difference between the two versions is a slight difference in angles, some minor differences in sound clarity and finally the "flat" widescreen version features more camera movement in order to capture all the action. Warner Brothers has released a 2-DVD set of this film containing both of these versions.
