Of course, this is a "revisal" rather than a straight revival.
From the article
Now I can't see the show working if Brigadoon only disappears for the first time in 1939. It messes with the whole premise of the show and I think that is better left alone.
But what about this contradictory casting notice? Do you all think this is merely a reference to the context of the original production? Or are we going have some time-travel? Or is the latest appearance/disappearance of the village going to be in 1939, during which Tommy and Jeff discover it, thereby giving the characters reasons to stay or go? There are things there that I find more intriguing than a conventional shifting of the time period of the original version of the show.
