Re: Assignment: Earth - Is it Really a Star Trek Episode?
It was always a strange experience for me in the 1960s to see Shatner and Nimoy in contemporary clothes, because I didn't really become aware of them until their Trek characters. Seeing Nimoy on a game show without the ears and penciled in "normal" eyebrows, or Shatner wearing a blazer with open collar shirt with his fancy sideburns always threw me a little bit back then. But apparently Roddenberry wanted futuristic hairstyles for the male actors as well, but they drew the line at that.
