And I seem to recall there was a battle surrounding the DICK TRACY novelization, with the studio not wanting the novelization to reveal who the Big Bad really was. Can't remember how it was resolved.
As I recall, Max Allan Collins (who was also the writer on the
Dick Tracy comic strip at the time) was oblique about it. Tracy unmasks the Blank & recognizes who it is, but the text doesn't explicitly say "The Blank was X." You could tell from the context clues, I think.
Also, from what I have seen of her original undubbed performance she really was not very good on stage. She wins the Harrison Ford "Most Improved" award. Only she did it on the same film! But Nimoy didn't experience that.
I was truly astounded at how flat her on-set performance was in the workprint! Goes to show just how important the ADR process is in film production.
I didn't realize that most of Kirstie Alley's performance in TWOK was looped. I've heard that she & Shatner didn't get along during production of ST2, but not that she'd had any problems with Nimoy.
I've long thought that Nimoy directed Robin Curtis to be flatter & less emotional in TSFS in order to kill off some of the fan interest in Saavik. After all, if Nimoy was returning to the franchise as Spock for who knows how many more sequels, he probably wasn't too nuts about
Trek fandom becoming enamored with a young attractive actress playing a new Vulcan character with emotional conflicts.
When Nimoy originally planned to leave
Star Trek after TWOK, sure, let there be a new Vulcan character to replace him, who cares? But if Spock was back on an ongoing basis, suddenly Saavik seemed pretty redundant. As Harve Bennett explained in an interview talking about why Saavik was written out early in
The Voyage Home, Saavik wasn't needed on the trip to the 20th Century, because she would've been "just one more pair of pointed ears to hide."
And it pretty much worked, as fandom had largely forgotten about Saavik by the time STV rolled around (she's not even mentioned in the film), and her character was "changed" to Valeris in STVI by basically doing a Search & Replace through the script.
I forgot about Stephen, but now that I've been reminded...yes, more atypical Vulcans who aren't related to Spock, please. Though I guess if you create enough of them the novelty gets lost.
That shuttlecraft left the bay a long time ago, IMO. But then,I've never really seen the point to any of the emotional Vulcan characters like Stephen, Sybok, and Michael Burnham. When they're from the same family as him, all they do is dilute Spock.
