Editing Star Trek: The Animated Series (section)

=== Casting and voice recording ===
''The Animated Series'' featured most of the original cast voicing their characters. The major exception was the character of [[Pavel Chekov]] ([[Walter Koenig]]), who did not appear in the series because the series' budget could not afford the complete cast.<ref name=RetFan1/> He was replaced by Lieutenant [[Arex (Star Trek)|Arex]], whose Edosian species had three arms and three legs; Lieutenant M'Ress, a female Caitian, sometimes stood in for Uhura as communications officer. Besides performing their characters [[Montgomery Scott]] and [[Christine Chapel]], [[James Doohan]] and [[Majel Barrett]] also performed the voices of Arex and M'Ress, respectively. Barrett also voiced various other characters and the main computer.<ref name="Burton"/>

Initially, Filmation was only going to use the voices of [[William Shatner]], [[Leonard Nimoy]], [[DeForest Kelley]], Doohan and Barrett. Doohan and Barrett would also perform the voices of [[Hikaru Sulu|Sulu]] and [[Uhura]]. Reportedly, when Nimoy arrived at the initial recording session for the first few episodes, he immediately noticed the absence of [[George Takei]] and [[Nichelle Nichols]]; when informed they had not been hired for the series due to budgetary reasons, Nimoy refused to voice Spock unless Takei and Nichols were added to the cast, stating that Sulu and Uhura were proof of the ethnic diversity of the 23rd century and should not be recast. Nimoy also took this stand as a matter of principle, as he knew of the financial troubles many of his ''Star Trek'' co-stars had experienced after cancellation of the series.<ref>{{cite book|title=To the Stars: The Autobiography of George Takei|url=https://archive.org/details/tostarsautobiogr00take_0|url-access=registration|first=George |last=Takei|year=1994 |publisher=Pocket Books|isbn=9780671890087 }}</ref> According to Scheimer, when Nimoy pointed out that the casting would cut the only two minority actors from the series, "We were horrified at our unintended slight, made all the worse because we were the one studio who had been championing diversity in its output." Takei and Nichols were quickly hired and the recording session was rescheduled. <ref name=RetFan1/> Koenig was not forgotten, as Filmation were able to assuage Nimoy's complaints on his account by buying a script from Koenig for one episode ("[[The Infinite Vulcan]]").<ref name=RetFan1/>

Voice recording began in June 1973, with the first three episodes recorded as an ensemble, i.e. all the [[voice actors]] for the episode in the room at the same time.<ref name=RetFan1/> Later episodes used the now more typical model of recording the voice actors separately to work around their other commitments. William Shatner and Leonard Nimoy, who were both touring in plays at the time, recorded their lines in whatever city they happened to be performing in and had the tapes shipped to the studio.<ref name=RetFan1/> Doohan and Barrett, besides providing the voices of their ''Original Series'' characters and newcomers Arex and M'Ress, performed virtually all of the "guest star" characters in the series, with exceptions such as [[Sarek]], [[Cyrano Jones]] and [[Harry Mudd]], who were performed by [[Mark Lenard]], [[Stanley Adams (actor)|Stanley Adams]] and [[Roger C. Carmel]] respectively,  the original actors from ''The Original Series''. Other guest voice actors included [[Ed Bishop]], who voiced the Megan Prosecutor in "[[The Magicks of Megas-tu]]", and [[Ted Knight]], who voiced Carter Winston in "[[The Survivor (Star Trek: The Animated Series)|The Survivor]]". Nichelle Nichols performed character voices in addition to Uhura in several episodes, including "[[The Time Trap]]" and "[[The Lorelei Signal]]".

Because of an unusual interpretation of the [[FCC fairness doctrine]], the premiere episode was not aired in the Los Angeles market. Takei was a political candidate for a seat on the city council, and [[KNBC]] feared that allowing his voiceover work to be heard would force the station to provide equal time for Takei's opponents.<ref>{{Cite news |last=Smith |first=Cecil |date=1973-09-10 |title=Star Trek Bows in Animated Version |pages=18, Part IV |work=[[Los Angeles Times]]}}</ref>
