The ape-like prosthetic makeup used for Michael Conrad (as "Creech") was created by famous Academy Award winning Hollywood makeup artist John Chambers, whose credits include Planet of the Apes (1968), Star Trek (1966), and The Munsters (1964). The latex mask used for "Creech" was an early prototype of what would later be used throughout the "Planet of the Apes" franchise through 1975.
