It was intended that Sulu's role be expanded in the second season, but owing to Takei's part in John Wayne's The Green Berets, he appeared in only half the season, his role being filled by Walter Koenig as the relatively young, mop-topped Russian navigator Ensign Pavel Chekov. When Takei returned, the two had to share a dressing room. The two appeared together at the Enterprise helm for the remainder of the series. There may be some truth to the unofficial story that the Soviet Union's newspaper Pravda complained that among the culturally diverse characters there were no Russians, seen as a personal slight to that country since the Soviet Russian Yuri Gagarin had been the first man to make a spaceflight. Gene Roddenberry said in response that "The Chekov thing was a major error on our part, and I'm still embarrassed by the fact we didn't include a Russian right from the beginning." However, documentation from Desilu suggests that the intention was to introduce a character into Star Trek with more sex appeal to teenaged girls.

Nimoy also had previous television and film experience but was not well known either. Nimoy had partnered previously with Shatner in a 1964 episode of The Man from U.N.C.L.E., "The Project Strigas Affair," and with Kelley (as a doctor) in a 1963 episode of The Virginian, "Man of Violence," both more than two years before Star Trek first aired. Before Star Trek, Shatner was
