<P> He was portrayed by seven - foot , seven - inch ( 231 cm ) - tall actor Lock Martin wearing a thick foam - rubber suit designed and built by Addison Hehr . Two suits were created , fastened alternately from the front or back so that the robot would appear seamless from any angle in the completed scenes . A fiberglass statue of Gort was also used for the close - ups of the firing of his energy beam weapon or when a scene did not require that he move . To maximize the height of the robot , the Gort suit was made with lifts in the boots . Martin could see forward through the suit 's visor area during certain shots , and air holes were provided for him under the robot 's wide chin and jaw , and these can be seen in several close - ups of Gort 's head . </P>
