These kinds of stories always make me think of the late Joan Winston's account of being on-set during TURNABOUT INTRUDER. Kelley comes off like an utter prince, no surprise, and it seemed like everybody was pretty nice considering they were all (except I guess Nimoy) going on unemployment next week.
I remember that, too. She had a huge crush on Shatner. The kicker was that she took pictures on the set and then the drugstore that was supposed to develop the film said they lost it. (More likely a technician in their lab stole the pics.)
