Dune (1984/2021) Side-by-side comparison; Trailer - 1 (Don't know if this has been posted before, but it still is too awesome...)
(Spoiler) Salusa Secundus in my opinion had the best atmosphere and theme, properly portrayed the sardaukar as a scary tyrannical army
Teaser Trailer catch it while it's still up: I sequenced the stills from the teaser with the audio first impressions by our favorite u/IDEASOFICEANDFIRE (IM me if it's down and you have a suggestion on how to share it)
