Unrelated to your comment, but it’s interesting that the older I get, the more I see older shows — sitcoms, WKRP, etc, Carol Brunette, and the 80’s & 90’s Star Trek series too…
…the more I see them NOW (literally now, as I’m watching the original episodes) I’m often imagining what the actors were experiencing creating and inhabiting these characters, and interacting with each other (as actors) both in and out of character. And what fun it must have been, or what it was like to ‘be’ these characters before they were fully developed.
Maybe it’s a byproduct of the VAST about of interviews now available online (both contemporaneous, and also years later in roundtable interviews, cast reunions, etc) — many of which are great fun and interesting to enjoy. There’s also a vast episode-by-episode fan wiki for damn near every Star Trek series, with tons of episode-specific quotes from actors taken from fanzines of the day, and Trek convention appearances and other interviews over the years. (Thus, NOW, it’s easy to imagine — almost hard NOT to imagine — the making of all those Star Treks while watching them.)
Anyway, it must have been incredible fun bringing those two Bob Newhart centered sitcoms to life — and Bob must have been such an interesting, VERY different and unique kind of ‘star’ to have at the center of everything.
