Hey there BIXBY -
Yes, perfectly stated on all counts, and I agree 100%; as it would take many small establishing 'bits' to flesh out her character' however since the producers were never interested in 'fleshing out a secondary' anyway, I limited the basic and immediate quandary of getting the UHURA character out of the chair, with something to say, and something to do - with proper motivation and justification.
HOWEVER,... like so many other things in STAR TREK, it COULD have been done, and wasn't,... and before you knew it,.... poof: CANCELED.
Interesting you cite RILEY,.. why do you suppose they developed his character - in just 2 episodes, as you say - and moreover, while letting UHURA rot in her chair?
Captain Tracy,
I don't know about a lack of interest on the creative team's part to develop the supporting actors. Just look at Chekov in 'The APPLE' where he got a nice little subplot (and make-out session) with Yeoman Martha, being the unwanted object of desire in 'The Gamesters of Triskelion', doing the usual Kirk bit in 'The Way to Eden'. And don't forget his never-ending and often hilarious references to Russia...
Uhura, as much as she appears a very warm and charming person, just isn't the most expressive type of actress. She could deliver her lines usually, but had a limited range of facial expressions...
I'd mentioned Kevin Riley before, and I agree totally with Redfern's assumption that Bruce Hyde's second appearance in The CONSCIENCE of the KING was more than likely pure chance. The character was likely renamed Riley because Hyde was available to play the part, but he could have been any number of generic crewman. The part in TCOTK was memorable and sympathetic because of Hyde's performance (note his face as he overhears McCoy revealing the presence of Kodos on the Enterprise, his desperate need for closure as he pleads to be allowed to shoot the murderer of his family).
Hyde's screentime in TCOTK is very small, but he completely made the best of it.
It's the same in The NAKED TIME, before he's infected he plays the part well, then ratchets it up as he goes crazy, walking thru the corridors (blowing open the sickbay doors was brilliant!), and singing ''Kathleen''. His singing was so outstandingly annoying they even made another crewman do the same thing to Janice Rand in a corridor, to a much lesser appeal...
Back to Uhura, in the Man Trap when she encounters a male black crewman, there was her chance to display some chemistry and appeal, but the final performance unfortunately marked her as too limited.
There's also been some discussion as to making her the Captain's confidante...the problem is I don't think Kirk could ever be open about his feelings with any woman. Plus that would have seriously curtailed his glorious skirt-chasing...
And two, we have to remember that Uhura is a lower-ranked officer. Showing any sort of preferential treatment like that would have started rampant rumours of an affair, or improper conduct. Not only would that have hampered Kirk's effectiveness as ship's Captain, but ostracized Uhura from the rest of the crew...
