In "Batman" (1989), the basic design of the suit, by Bob Ringwood, is essentially the Neal Adams version of the costume, which was still in vogue in the comics during the 1980s. This movie suit was notable for its introduction of the grapple gun with a motorized reel (which was later adopted by the comics), for the black eye makeup worn under the mask (which has been used in every live-action Batman film since), and for the construction of the cowl (which made it nearly impossible for Michael Keaton to turn his head while wearing it). The costume was constructed of black kevlar-like material over metal plating (layers of foam-latex over a Neoprene bodysuit in reality, hi-tech body armor in the context of the film), instead of the light-gray spandex seen in the comics and in the 1966 live-action "Batman" television series. Keaton was told not to put on too much muscle in preparation for the role, as there was uncertainty to how it effect the costume they were sculpting on bodycasts made during the filming of "The Dream Team". Keaton's lean build proved helpful when adding layers of armor to his silhouette with the bodysuit.
