Robinson was originally cast in the role of Dr. Zaius in Planet of the Apes (1968) and he even went so far as to film a screen test with Charlton Heston. However, Robinson dropped out of the project before its production began due to heart problems and concerns over the long hours that he would have needed to spend under the heavy ape makeup. He was replaced by Maurice Evans.
