For the first time in the history of American TV, an announcer is heard over the closing credits of a network TV program, reassuring viewers that the show (in this case, Star Trek) has been picked up for a second season – and making a direct request that the series’ ardent fans bring their concentrated letter-writing campaign to an end. That campaign has actually been secretly organized by Gene Roddenberry with the help of several prominent SF writers and Star Trek fan Bjo Trimble.

Dot Records releases the Leonard Nimoy‘s album Mr. Spock’s Music From Outer Space, a collection of songs both in and out of character as Spock. Aside from providing material for future Golden Throats albums, this record sparks a feud between Nimoy and Roddenberry; Roddenberry claims co-writing credit on the Star Trek theme (which is featured on the LP) and credit for creating Mr. Spock, and demands – to coin a phrase – a piece of the action.

During otherwise typical contract negotiations in preparation for the second season of Star Trek, Leonard Nimoy’s agent demands a significant raise for his client – a raise that could well break the back of the series’ already-struggling budget. In response, Gene Roddenberry, Desilu Studios and the show’s producers play hardball, firmly suggesting that Nimoy be satisfied with a normal raise, and they prepare to recast Spock or create a new Vulcan character to replace him. The show’s casting director suggests numerous potential replacements, including Mark Lenard, Lawrence Montaigne, David Carradine (Kung Fu), and Henry Darrow, among several others – all actors who are felt to have a “Vulcan look.” Nimoy – only later learning what demands his agent has made – negotiates his return to the series, while Montaigne is interestingly cast as Spock’s rival in the second season premiere, Amok Time. Henry Darrow will also don Vulcan ears, but not until Star Trek: The Next Generation’s first season.
