There was a recent discussion in /r/TheCulture about who Culture fans would like to see direct a movie adaptation of one of the books [1]. I'm dubious a live action film could be successful and at the same time live up to one of the books; it would take some mighty fine screenwriting to not slip into excessive expository minutiae about The Culture, and so much of the attraction of the books to many fans was the reader wasn't repeatedly hit over the head with explanations of the setting.

Any movie treatment of The Culture runs the constant risk of only getting the glossing highlights reel version that Dune received, and I'd be concerned that the mechanics of the story setting, neat as they are, in a movie would get in the way of telling the real story of Banks' more interesting themes via his incisive commentary delivered by holding up The Culture mirror-like, comparing to our own civilization.
The earliest science fiction I recall set in a post-scarcity environment is "Star Trek: TNG". Granted, the socio-economic impact of replicators is not a focus of the series or the movies, replicators are more of background/world-building device ("Tea, Earl Grey, hot")
Even more important than the sheer existence of the Minds was their egalitarian disposition and relationship to their pan-human co-citizens, and interesting tangentials like the Minds' polite yet firm declination to Sublime. I will sorely miss Banks' weaving of the tales of the proto-Culture, and how the early Minds came about to that position.
Post-scarcity and post-singularity are orthogonal - The Culture is both, Star Trek TNG is post-scarcity only, Rapture of the Nerds[1] (Stross & Doctorow) is post-singularity only.

I do think Use of Weapons could make a splendid movie - but it might be tricky hiding the basis for the twist at the end?
Use of Weapons might work too. I can't see Player of Games translating to the big screen well, though. So much of it is about the game itself and the protagonist's thinking around it. And I do think the rest would be hopeless.
After posting that comment I spent a while wondering which novel would be best to jump start that sort of franchise and agree it's tricky to condense a novel into a movie. A lot of science fiction probably works better as a mini series or full TV series (could be interesting to have Culture take an approach like American Horror Story where each season is a self-contained story)
If only animation automation got sufficiently good and economical enough that long-form (40+ hours) video storytelling was practical for more stories. I sometimes wonder if there is a Sapir-Whorf-style equivalent hypothesis for how we exchange our stories, where the storytelling modality (starting with just the time length our formats allow, but going much further afield with complexity management/expectations, formulation of models, etc.) shapes how our aggregate civilization thinks.
It's how they deal with not having the budget to actually put people in a desert so it's rather visibly a desert backdrop at some points, it's why the lighting is often so strong and monochromatic like a theater's lighting, it's why the acting is with all the characters projecting as if they are speaking to an audience rather than in a TV production. At one point they even use a very theatrical special effect based on backlighting through a thin cloth representing a tent to show Paul's hallucinations/thoughts, rather than even a simple bluescreen or conventional image compositing effect.
The effort is interesting, but I'd have to call it ultimately a failure (even if I personally ultimately enjoyed it) as it almost completely failed to speak to its audience. I also think you can't really follow it if you didn't read the books, which I consider a major flaw of an adaptation.
But I agree, there are some pretty bad films being made under the science fiction genre. I want movies referencing hard science fiction (was wondering the other day what an adaption of 'The Three-Body Problem' might be like) and space operas too (Culture series is dying for a film adaption).
But in terms of science fiction, I think it's great seeing non-space material being made too. Stuff like 'Dark Mirror', 'The Man from Earth', and 'Safety Not Guaranteed' are pretty good indicators to me that good science fiction has gone mainstream.
