Sorry for re-opening this, just to clarify...

1. I initially copied the cast from the other TMDB page, simply for efficiency, not anywhere else (the movie has been out for quite some time, so I had no reason to doubt the validity of the cast list. Nor that it would change too much in the "Netflix miniseries re-imagining").
2. I had a chance to watch the miniseries, and edited the cast list to match the end credits exactly. The end credits are identical for all three episodes.
3. The small handful of cast members who were not listed became "uncredited" and left there, since I often see... well... uncredited cast members on TMDB.

Hope that makes sense, nothing dubious or bogus done/intended. Cheers. (Please close this thread again, mods.)

It looked highly improbable that all 30+ actors are the regular cast members as the bible describes that https://www.themoviedb.org/bible/tv/59f73eb49251416e71000022

Right, I can see that. This is a mini-miniseries, if you will. Three episodes that are really "parts", no opportunity for anyone to not be a regular cast member. It was accepted as new content due to the whole adaptation-to-series aspect (à la Das Boot / Das Boot), Netflix's involvement, its listing in TV apps using TMDB data, avoiding confusion, etc.
