So this new one is a remake of the 1984 one.
There is also a SyFy mini series that covers the same.
So they are same story/timeline as each other, although this new one is just the first half.
That makes sense...but how does 1997's Spice World fit into either timeline? Is it a prequel? Sequel? An Arrakis related side story (like Mandalorian and Visions with the SW Universe).
Is it important to watch Spice World before I see the new Dune?
