Dungeons and Dragons: Under a Dark Sun
Introductory Narration, Conan Style. Get someone with a beautiful and strong voice that people can recognize pretty easily.
The initial narration includes the idea of Vile Sorceries, Psionics, and a world ravaged by dark Sorcerer Kings whose madness and genocides have left little behind save squabbling city-states ruled by those same villainous madmen. Too powerful to oppose they ruled for centuries without real challenge, until the Heartblood Spear pierced Kalak and toppled the Sorcerer King of Tyr. Some notes about the Fragile Freedom of the city-state, and how Kalak's death has been a rallying call to Preservers and those who wish to be free.
Whole movie about fascism, climate change, and the rise of anti-authoritarian forces told through a Hopepunk story in a bleak world where the heroes fight against and use some of the colorful local beasties (Braxats Thri-Kreen, Mellikots, Half-Giant companions, etc) and work to unseat a Sorcerer King. Mostly non-white cast. In a desert, Lily Whiteness is a bad thing. Tall pointedly not-white elves? We need more of it!
Ditch the rest of the Prism Pentad, though. Just have the Kalak death thing be canon and write the film as "In the wake of" type stuff.
I would watch it.
