Couple of things, I guess.
I didn't suggest that Fanon's analysis should somehow be "embedded" wholesale in the adaptation, just that many points of that analysis find correlates in DUNE as it's written, which is perhaps unsurprising as each work was written by a worldly intellectual in the same era.
I don't think it's too hard to imagine a work of fiction representing Fanon's unorthodox Marxism-Leninism though.
DUNE is a problematic work. It's notably weird in its fixation on gender, has a eugenicist outlook on human potential, and its politics are reactionary almost to the point of fascism. However, it's also a notable and interesting work because of its revolutionary and environmental themes. It's worth a read, though you'll find plenty to laugh at. Herbert's decision to turn his science-fictional oil, the "spice", into a metaphysical device for human ascension is fascinating.
My take is if you're going to adapt DUNE it could be a critical adaptation informed by the thinking of Fanon, Robert Vitalis, maybe Patrick Wolfe, Ghassan Hage, and plenty of others. I haven't seen the new adaptation yet, but I know just from the trailer that the casting sets the "Fremen" (an oppressed indigenous desert people inspired by the Bedouin and depicted in the text as highly culturally and racially uniform) out as a diverse, colonial society—a move seen by liberals as progressive. To me it's a choice that squanders the potential for a contemporary audience to connect the material more clearly to empire and colony and its historical origins.
Likewise, the novel features a depiction of extractive capital at scale: not the scale of individual "harvesters" for example—as we're seeing Villeneuve's adaptation makes everything Gothically "vast"—but the logistical and ecological scale, the number of vehicles, the way they are maintained and stored, the profits being drawn, the violence required to sustain the process, the complicity of ostensibly "good" actors in this system, and so on. I'll be interested to see if the film takes any of that on, but I suspect it won't.
Given the corresponding scale at which such a massive Hollywood blockbuster pumps out ideology to its audiences, it's a shame.
