I remember at my screening, there was a group of three guys sitting a few rows down from me who kept pulling their phones out and texting throughout the movie. It's true what they say, the light from a phone's screen can be very distracting in darkened theatre.
Ages ago when we went to see Tron 2 3-4 guys in the row in front of us were very loud - don't care when they do that during the commercials or even the trailers but they continued when the movie started.
I was with a group of friends and all of them had quite some mass and size, including me. So a few minutes in and they continue to be dicks so a friend leans over and says to them to cut it out in a very direct manner.. one of them turns around to obviously start some crap and sees this group looking like professional bouncers and immediately shuts up.
Quite satisfying
I think some people have too much time on their hands and it leads to the following article.
One of the points made by the author is that Herbet borrowed nams and terms from Islam and the North Africa/Middle East region but Villenue didn't cast as any actors from the region as Fremen and the both film versions have involved a great deal of white washing.

I have never bought into the notion that Hollywood needs to be the leading edge for social change or even inclusiveness.
Actors are hired to act in movies, in one movie they are a mass murderer, the other a victorian Butler and the next a soldier in WW2 and the list goes on.
Why should it be a prerequisite to belong to a certain group to be able to play a role? If playing a historical figure some things shoud match, you can't have a super white person play Martin Luther King for example ( or you can if you want to make some kind of experimental movie or an artistic statement).
I understand that people want to be represented on screen, to see their culture onscreen and possibly "their" actors too - for far too long Hollywood was an exclusive white club, it took them decades to even recognize people of color as other than background characters or plain racial stereotypes. This development has gained momentum in recent years, though i'm cynical in that regard because Hollywood is huge business and being "woke" means just doing it to avoid social media backlash and possibly testing the waters if it impacts revenue positively.
In the end even Dune is about business.. Javier Bardem is an easy choice because he is a tremendous actor, has an established name and is recognized by the audience so why not? Villeneuve could have broadened his actor's pool but then again why would he?
This is not a movie about muslim culture, the Fremen stand for all indigenous people, they just have an islamic focus because at the time of writing these books the islamic world was considered very exotic and foreign.
