I left Star Trek in the third season.I left the show. Nobody thought it was going to be picked up anyway, so nobody really cared.I left for a month and I did a play outside of Chicago with Jackie Coogan, Charlie Chaplin’s old sidekick, and that was great fun. And I didn’t miss being on the show because, at that point, it was really, ‘Aye aye, sir.’ And I still wanted to perform in my chosen profession with some dignity. Dignity of participation.
Why Walter Koenig Left Star Trek: The Original Series In Season 3
Walter Koenig appeared as Ensign Pavel Chekov in 16 ofStar Trek: The Original Seriesseason 3’s 24 episodes. As he explained duringThe 7th Rule’s review of “The Trouble With Tribbles,“Star Trek’s supporting cast like James Doohan, Nichelle Nichols and himself got to shine in that comedic romp. However, this wasn’t often the case, and there was even less focus on characters like Chekov, Scotty, and Lt. Uhura inStar Trek: The Original Seriesseason 3.When Koenig left midway through season 3 to do a play,Star Trek’s cancelation by NBC was expectedand came to pass.
Star Trek: The Original Seriesprimarily focused on the lead trio of Captain James T. Kirk (WIlliam Shatner), Mr. Spock (Leonard Nimoy), and Dr, Leonard McCoy (DeForest Kelley). Walter Koenig had moments to shine as Chekov, but as he would often lament,much of his role was reduced to saying,“Aye aye, keptain"in manyStar Trekepisodes. Koenig also felt the lack of attention to the supporting characters continued into theStar Trekmovies. Walter has long noted that he desired to do more inStar Trek,and have the"dignity of participation,“as he phrased it onThe 7th Rule.
