The first challenge will undoubtedly be the fact thatMessiahtakes place a whopping twelve years after the originalDunebook.
The ending ofDune: Part 2also implies a somewhat different role for Chani (played by Zendaya).
It is this love triangle that creates the primary driving plot of the second book.
She joins the cast as a main character inMessiahand also operates a major side plot of the book.
Its also possible that the teenage Alia could be recast.
Paul will retain and work with his visionary abilities throughoutMessiah,too.
This, however, puts his familys rule in peril.
Also returning for the film will be Duncan Idaho, played by Jason Momoa.
One character in particular wont even need to do any off-screen aging at all.
