One of my all time favorite "hard" sci-fi books.
There has been talk for years of a film; most recently Morgan Freeman had supposedly taken the helm, but I've heard nothing more since. A teaser trailer on YouTube from 2015 notes a 2023 release.
I'd rather have them take time and do it right rather than rush it and leave us with another Dune.
Loved it too, except for the ending. Because of that ending there was an unpleasant sequel.
Wasn't there more than one sequel?
