I'm out of the loop with Dune news. Is the plan still that Dune Messiah will cover the second book (of the same name) and there'll be a Children of Dune TV show? Or am I just speaking fake news?
I think the Dune: Messiah movie is still in early development but the idea would be for it to cover the second book, yes. The TV show is based on one of Brian Herbert's prequel books about the origins of the Bene Gesserit 10,000 years prior to Dune 1
