Anne,
I think that the late Diana Millay guest-starred in almost as many American tv shows as DS’s MOST prolific actor, Dennis Patrick.
That “Star Trek” actor you were referring to was most likely the late DeForest Kelley, who was the seemingly perpetually grumpy Dr. Leonard “Bones” McCoy, Mr. Spock’s “good” buddy on the Star Ship Enterprise.
Incidentally, I remember seeing a cartoon in one of the DS fanzines, where we see Captain James T. Kirk after he had just beamed down (apparently) accidentally to the Eagle Hill Cemetery and we see Kirk speak very desperately into his communicator, shouting:
“Scotty, Beam me up,
NOW!!!”
