This website was news to me, so maybe it'll be news to many of you too:

It's a really comprehensive collection of photos of the Desilu backlot, where exteriors for shows like
The Adventures of Superman,
The Untouchables and
The Andy Griffith Show were filmed.
Depending on how much you like
Gone With the Wind, you'll either be exhilerated or depressed to see how its surviving sets slowly deteriorated over the years. There seems to have been a conspiracy of indifference that allowed old movie sets to remain in place, even when they were literally falling to pieces (standing sets from as far back as
The Godless Girl (1929) survived for decades). But, predictably, not a trace of the backlot remains today.
Kudos to Marc Wanamaker's Bison Archives, which supplied the bulk of these photos.
