Earlier British science fiction series with marionettes and soap operas had interracial casting, but this was the first American live-action series to do this. At a time when there were few non-white or foreign roles in American television dramas, Roddenberry created a multi-ethnic crew for the Enterprise, including an African woman (Uhura), a Scotsman (Montgomery Scott), an Asian man (Hikaru Sulu), and—most notably—an alien, the half-Vulcan Spock. In the second season, reflecting the contemporaneous Cold War, Roddenberry added a Russian crew member, Pavel Chekov (played by Walter Koenig). The original series is also credited with American television's first interracial kiss, between a white man and an African-American woman, although this had happened earlier in a British medical soap opera, "Emergency – Ward 10". Also, the spy series "I Spy" featured a scripted, unedited interracial kiss between Robert Culp (white) and France Nuyen (Vietnamese) in the episode "The Tiger"; a kiss that would not gain the controversy or attention as the "Star Trek" kiss did.
