If all this is true, I was unaware that William Shatner felt threatened by the popularity of Leonard Nimoy's popularity as Spock during the original series. Certainly, Shatner as Captain Kirk was very popular as well with viewers of the show, to the point that he should not have felt threatened by Nimoy's popularity.
The George Takei/Shatner feud we all know about. Likewise the Ellison feud with Roddenberry and the series producers over "City On the Edge of Forever". Some of the others surprised me.
