Some other things Brian FH Clement mentioned in his tweets (I can't find them on Twitter but found them on screen-grabs on Instagram):
- Cast looks phenomenal in their costumes.
- Dave Bautista has never looked creepier.
- Set design has the same "big feel" of BR2049 and Arrival.
- Mix of grimy realism + dreamlike imagery.
- Baron Harkonnen looked cool.
- Saw lots of Paul in his stillsuit.
- Actor playing Dr. Kynes is not a huge star but an established actor.
- He saw Dr. Yueh, Rabban, Paul, Leto, Stilgar, Gurney, Duncan, Jessica, some Fremen in stillsuits and either Sardaukar or Harkonnen personnel.
- Rebecca Ferguson looks cool and kind of eerie.
- Oscar Isaac looked cool, a different look to what we're used to seeing from him.
- He saw an ornithopter and it doesn't look like the ones in Lynch's version.
- There were wide shots of a group of people featuring Rabban and probably Harkonnen personnel as they had similar costumes and make-up.
- Title looked like originally created artwork and not some standard font.
- He saw sandworms.
In other news, it seems like Brian Herbert has another novel coming this October 27 called 'Dune: The Duke of Caladan.'
