I got the video for it. It was sent out to press people, so it should be going up online soon if it isn't already.
Overall, liked the trailer. Definitely seems like they are expanding Duncan's role and making him a more Jason Momoa type of character.
I think the worms look great.
That said, I didn't like the final music cue in the trailer. It didn't sound like Dune to me. But it's just the random music cue in a trailer.
Also, I'm still not convinced this will be a hit with audiences. But in this pandemic era, who knows.
