I always find it funny that during the production of TOS, Nimoy also line counted, made demands, and took advantage of his swelling popularity--it was about himself, not the supporting players (he did not become their official champion until the casting issues surrounding the animated series), yet they do not attack him, when his own demands certainly (in the big picutre) limited the supporters' weekly parts.
An excellent point.
But did he intentionally tank a scene with Takei that would have given him (Takei) command of a starship 4 films earlier than VI? Hnnh? HNNH!?
At least I think I read that.
