The development of Spock, a fictional character first introduced in the American science fiction television series Star Trek, began prior to the start of the series. The first known mention of Spock was in a discussion between Gene Roddenberry and Gary Lockwood, where the latter suggested Leonard Nimoy for the role. Roddenberry agreed with the suggestion, and Nimoy became the first choice actor for the part. However, Roddenberry was required to audition other actors for the role. It was offered to both DeForest Kelley (who would eventually play Dr. Leonard "Bones" McCoy) and Martin Landau before Nimoy. Nimoy disliked the prosthetic ears he was required to wear, and there were concerns from the studio that they made him appear satanic. Roddenberry fought to keep the character in the second pilot, "Where No Man Has Gone Before" after the rest of the main cast was dropped from the initial pilot, "The Cage".
