As far as differences between the 2020 and 1994 miniseries versions of The Stand go, one notable aspect revealed in the new trailer is the appearance of Nick Andros.
Is it possible that he is looking up at a levitating Randall Flagg (played by Alexander Skarsgard)?
That’s an interesting thing to know, but what it doesn’t address what the hell he is staring at on the ceiling in his brief appearance.
