Few actors are as inextricably associated with one role as Leonard Nimoy is with Star Trek’s Mr. Spock. In 1975, when he was embarking on a post-Star Trek career, Nimoy published an autobiography with the tongue-in-cheek title I Am Not Spock. Twenty years later, despite a fruitful career as a film director (Three Men and a Baby, The Good Mother) and theatrical actor, he here reembraces his legendary half-Vulcan alter ego. Star Trek fans will find this a, well, fascinating history of the “birth” and evolution of Spock?Nimoy explains the original conception of the character and describes his own contributions to the development of Spock’s persona. He also provides an insider’s account of the production of the TV show and the highly successful series of Star Trek movies, and offers his insights into why the Star Trek phenomenon has maintained such a grip on our cultural imagination. Nimoy’s admirers may find this fairly impersonal memoir disappointing; it touches only tangentially on the author’s private life. But this is an intelligent and entertaining look at an actor’s engagement with a character who “seemed to take on an existence of his own.” Photos. Author tour.
