Like Mummelman, I'm also stoked to see this in IMAX.
My only gripe would be Feyd's bald head. Sting's look in Lynch's Dune felt appropriate given how he's the Harkonnen's best option to marry up. Oh well... Uggo Butler it is.
I don't mind the bald heads as they'd already established that's the new Harkonnen look in part 1. It anything bothered me it's Chani wearing a light blue headband; the last thing I expect to see in the deserts of Arrakis is bright coloured clothing. Also curious why Paul doesn't have blue eyes for most of these scenes, as he should've been in the desert for years at this point, and even Lady Jessica is shown with blue eyes throughout the trailer.
On the positive, I'm glad they seemed to have based Princess Irulan more on the SyFy version where she's actually involved in the story-- convinced there's a connection between Muad'dib and the presumed dead Paul Atreides, actively searching for clues and connections using her bene gesserit skills to manipulate people --as opposed to the book version where she's just a figure head who only pops up in the end.
For Paul’s eyes, there 2 explanations. First, while do his eyes get the blue shade slowly over it’s stay in the desert, they become completely blue once he undergoes a certain process. The difference between him and Jessica is that she will undergo that process way sooner than him.
Second, the trailer is probably made like this on purpose. Since DV will probably explore the 2 year gap, showing the shade of blue in the trailer tell us what happens and when. The only time we see a full blue in his eyes is in the scenes that we know exactly when they happened like the duel with Feuyd.
The interesting thing with Irulan, she’s probably have a bigger presence in the movie because DV is setting up the framework for Messiah and make his job easier by fleshing her out now. Damn I hope WB won’t be idiots and let him completes Paul’s journey.
