Whenever a movie starts with a Part One in it’s title, I get a hesitation. And Dune’s only covering one half of the FIRST book. This was going to be slow, this was going to have a lot of filler, this was going to have information and scenes that are not at any point integral to the main story and it won’t be very pretty because they would save most of the budget for the second film.
The thing about that is that there was a very good chance Dune part 2 never got made if the first didn’t do well enough, so there was a lot of motivation to make it as good as it could be. Dune was kind of a redemption attempt after Villeneuve’s Blade Runner 2049 (unfairly, imo) flopped.
You need to stop thinking laws are inviolable writ handed down from God. We’re all playing a game of shared make believe where the rules are only strong as the collective will to enforce them. That will doesn’t appear to be sufficient so he can likely do what he wants.
