The head of the creature costume were first sculpted in clay and then covered in a plaster cast. Once the cast was removed, liquid latex was applied to create a flexible single piece mask. It was then painted, and Wah Chang
added a white wig and attached glass lenses to the mask for eyes. Once Sandra Lee Gimpel
was wearing the mask, cuts were made into the wrinkles in order to offer the actress some limited vision while wearing it. A pair of gloves were modified by Chang to give the fingers the appearance of tentacles with suction cups. William Ware Theiss
created the rest of the costume out of a fur bodysuit. See more
When Kirk jumps out from behind the rock after stunning Crater with his phaser, the large "stone masonry" structure next to him wobbles when he nudges it, revealing it's fake. However, the rock on planet M-113 may be volcanic rock or rock such as pumice which is lightweight and the stone masonry made of such, and thus, movable. See more
Captain James T. Kirk
Captain's log, stardate 1513.1. Our position, orbiting planet M-113. On board the Enterprise, Mr. Spock, temporarily in command. On the planet, the ruins of an ancient and long-dead civilization. Ship's surgeon McCoy and myself are now beaming down to the planet's surface. Our mission: routine medical examination of archeologist Robert Crater and his wife Nancy. Routine but for the fact that Nancy Crater is that one woman in Dr. McCoy's past.
