And it's interesting that TFF is being used as 'evidence' of Shat's ego: From what I hear, it was exactly the opposite. Most of the rest of the cast had high praise for Shat as a director - that he was a professional at all times, treated everyone with respect and courtesy, and there was never any of the baggage normally associated with him as a co-star.
I've heard this, as well. My understanding is that Shatner went out of his way to make sure each of his co-stars had at least one memorable scene in the film, something that wasn't the case when either Nimoy or Meyer was directing.
I really hate this kind of bitching about Shatner for decades. I hate to break this to Koenig, Takei, Nicholls and Doohan...but they were extras. Glorified extras.
Shatner, Nimoy and Kelley were the main cast [in that order]. When the others talk about 'being held back' or whatever I can't help but laugh.
This. As much as Takei and Nichols want to believe that TOS had seven stars, it really had only thee. What's more, it's unlikely the four co-stars would have gained the attention and popularity they have without Shatner and Nimoy carrying the series.
Star Trek has given each of them opportunities they'd likely never have had; blaming one of the people who made the series what it is doesn't make sense.
