... When binging Star Trek, Bonanza, Adam-12, whatever, I Google the actors, original airdates, even the businesses in the background on location shoots (especially cool for Adam-12 and Emergency).
Yeah, I do that too, but usually just for actors I've seen somewhere before and, heh, the good looking actresses...
This summer I've watched more TV than I usually would, with the virus and all shutting everything else down. At least they ended up running the Tour de France, which is always great and just took up three weeks with evening recaps.
I haven't really watched many old shows until this year, although I do like them. it's interesting how many different shows some of the actors made appearances in, and how many went on to have shows of their own.
