Golf clap.
I propose Dune-Nuts.
I actually looked to see if there was an equivalent of “Trekkies” for Dune fans and there doesn’t seem to be. Then again, even Star Wars fans don’t have an official nickname. Not everyone in geek culture gets a nickname.
Nerds?
The sequel is officially greenlit, probably looking at 2 years. Exclusively in theaters.
My biggest problem with the movie.
I enjoyed it, but I feel so much info was cut that someone who hadn’t read Dune wouldn’t have enjoyed it like I did.
My favorite scene was probably the size of a sandworm (the first one), done really well. Before I thought maybe you could “dodge” one because I wasn’t sure how big it was. Umm… nope. Hell no. Scattering won’t help either, you just can’t run fast enough to escape that giant mouth. You would all get eaten.
Speaking of worms, when I was watching, I wondered why they don’t just feed the worms some explosives. It happily ate the harvester. (By the way, why? Is metal nutritious? On that note, what does a sandworm live on? It’s so big, it would need a lot of biomass to get that big) So why not fill a harvester full of explosives and feed it to a sandworm. These humans are capable of interstellar transit and they can’t kill a worm?
Well, because the worms make the spice
It’s part of their reproductive cycle. Gravid female worms thump to attract a male. The male eats the female. The eggs are fertilized as they pass through the male’s digestive tract.
Sandworms directly metabolize chemicals in the sand. Basically a huge furnace that breaks down and recombines everything in the sand. Compare to whales.

Actually I thought they ate sand the way worms eat dirt. After all, they’re worms, except really big. And worms (in Dune and real life) are a part of the ecosystem. I won’t go into more since it’s very spoilery (as @Pork_Rind appropriately noted).
Sand plankton. Really. Don’t ask…that’s just what they eat.
IIRC, the worms reproductive cycle is a biological Modest Proposal, just with giant worms and sandfish.
You are absolutely right. The guy can’t enunciate to save his life. And he looks like he was created by a committee: good hair, has an interesting (pretentious) name, looks a bit like a young Tom Hiddleston, let’s make him a star!
Wow, no. I thought he was fantastic. Could completely buy him as young, inexperienced royalty.
Has anybody applied the cube-square law of animal proportions to sandworms? Seems to me that something that large shouldn’t be able to move, much less do what they do in the book. That has always bugged me about the ecology of Arrakis.
The harvester is really big, so filling it with explosives would use up a lot of explosives.
I imagine many smaller explosions wouldn’t even reach the guts (if you dropped them from the inside). If you filled a box filled with explosives and shrapnel, and they didn’t reach the guts (just blowing up in the space within) I’m not sure the worm takes any damage. If you blew up part of it, perhaps it would simply shed the front part of it. (They’re not actually earthworms, which can survive losing segments.)
But as others pointed out, you don’t want to kill the worms. The strategy they typically used works as long as your carryalls are in good repair.
They survive via the Rule of Cool. That’s all.
IIRC sand worms move by generating an electric field which makes sand near them push apart so easy to move in. Ever hear of soil liquefaction (real thing)? Basically they get sand to do that when they are around. In the movie I think they use the vibration bit as you see Paul and Idaho start to sink in the sand as if in an earthquake which is how real soil liquefaction works. I want to say in the 1984 Dune we saw lightning around them (so the electric thing) but it’s been a long time so not sure.
As for being able to support their own size…science fiction (I mean…it all is).
I just tried re-watching it. I really can’t stand a single moment when his voice is on the soundtrack. He just ruins every moment he speaks.
Nuke them from orbit. It’s the only way to be sure. 
Rule of Cool still rules. It’s been decades since I read the books, so I don’t remember. Do the books ever give dimensions for either the harvesters or the worms, other than “Big. No, really fucking BIG!” Just speculating that the movie makers may have bulked up the size for more visual spectacle. Especially since you ride a worm by tugging open sections of its skin with hooks that are something that can be personally wielded. Don’t think you could do that with something the size of a mountain. Too much mass for a single person to move.
Males: up to 400m long with 100m diameter. Females: up to 100m long with 20m diameter.
