well known in the trade, having appeared in several notable films, played Cyrano de Bergerac on Broadway, and even turned down the part of Dr. Kildare. However, when roles became sparse he took the regular job after Jeffrey Hunter's contract was not renewed. After the original series ended, cast members found themselves typecast because of their defining roles in the show. (Star Trek: The Next Generation actor Michael Dorn stated in 1991, however: "If what happened to the first cast is called being typecast, then I want to be typecast. Of course, they didn't get the jobs after Trek. But they are making their sixth movie. Name me someone else in television who has made six movies!")

Spock, however, went on to become one of the most popular characters on the show, as did McCoy's impassioned country-doctor personality. Spock, in fact, became a sex symbol of sorts—something no one connected with the show had expected. Leonard Nimoy noted that the question of Spock's extraordinary sex
