To the surprise of the production team, Barrett appeared normal flesh colored in all footage. They tried again, applying a much darker shade of green. Once again, when the results were received, she didn't appear green at all. They tried a third time and the same result was received. Roddenberry phoned the development lab out of frustration, only to hear their surprise that the character was supposed to be green. They had presumed that the cinematographer had set up the camera incorrectly and had spent a great deal of time correcting Barrett back to a normal color. A number of actresses were considered for the part, including Yvette Mimieux, Yvonne Craig, Barbara Eden and Anne Francis. Roddenberry's first choice was Susan Oliver, whose talent agency said she was an excellent dancer. She was convinced to take the role by Oscar Katz, an executive at Desilu Productions. He didn't attend the set in an effort to avoid Oliver, since he had undersold the difficulty of the makeup in the role.
