Blast from the Past!
Roddenberry’s company is releasing pieces from their “vault” about early days of Star Trek. One letter shows some of the considerations in having Klingons as the heavies in the future. Good heavens! Might we have lost our Klingons???? By this time, 1973, the original series had been cancelled and was entering immortality under syndication. The animated series started in 1973.
I wonder what in the guilds meant Klingons had to be “fully humanoid”.
