I thought DV had a 'free pass' on this one to make both parts? He said in some interviews earlier this year it was a pre-condition on him even starting the project that WB would let him make both movies regardless of how the first did.
We've also got the HBOMax series coming about the Bene Geserits, not sure how delayed that is by Covid though.
Yeah he refused to direct it unless he could split the book into two films which the studio acquiesced to. However I can't see them wanting to pump money into part 2 if the first one bombs. BR2049 actually did okay globally despite it's perception as a disappointment financially, so as long as it does as well or better (which it should as it's less of an art house love affair) then we should be good to go.
Personally I'd really like DV to film Dune Messiah and Children of Dune for consistency - which can both be told in single movies... I'm not sure since God Emperor is really, really not film-friendly (although I love it), Heretics and Chapterhouse are but there's a long way to go before we're anywhere near talking about those.
