One of the disappointments of my life is that there aren't 20 or a hundred films like Blade Runner
Oh, I don't know... There's the Alien trilogy. That brings us to four, including Blade Runner. Then there's Ghost In The Shell (I know the genre is slightly different, but it's good none the less and has a similar theme). That's five, and that's just off the top of my head. I'm sure that if you and I ransacked our movie shelves, we'd find at least ten different SciFi moves of that calibre.
Considering how many Dunes have been made, one should think that at least one of them would be reasonably good. Alas, that doesn't appear to be the case.

Allmovie files this film under tech noir. Of that list, Dark City definitely has a similar atmosphere. The 'similar movies' listed on the film page are not all that similar, though The 5th Element is a bit similar thematically. Brazil, maybe a bit stylistically, though it has more absurdity that punctuates the atmosphere.
Now on Amazon, the customer recommendations for the version with the highest sales include Dark City, 12 Monkeys, The Road Warrior, The 5th Element, and Alien. IMDB does not come up with good suggestions (although I can't tell for I, Robot and Xscape because I haven't seen them).
But of all films mentioned, the Ghost in the Shell animes are closest, they are practically in the same Universe (only a decade later and on another continent). Which brings up Matrix as another association, having stolen so much from GitS (something I realised oly recently, having watched it for the first time only a few weeks ago). *Traitor*, n. A benighted individual who perceives an illusory distinction between serving his nation and abetting the criminals who govern it.
(as a partial offside, both GitS and the sequel quote heavily from the Bible; though in GitS this is hidden. But read 1 Corinthians 13. It's a good piece or prose/poetry (probably from a pre-new testament source) and via certain associations it will bring you to Three Colours)
