Just seems like the way to go. Practical sets, you can shoot some wide stuff in a real city but the claustrophobic street-level stuff could pretty easily be a sound stage like in Dark City.
Neon's great, just...sleazy gritty 20th century neon, don't go all cutting-edge-tech Seoul/Tokyo/whatever hyper-modern. Saw Vancouver suggested up there, Vancouver's probably way too "clean", lots of glass buildings & modernity. Skyscrapers are great and all, but go more Empire State Building than, you know, One World Trade Center or that recent one in London.
Agreed on the miniatures, maybe even matte paintings, Boom. We probably both know that's never gonna happen though.
2019, greenscreen bullshiz it shall be.
Came across that on google, no idea where it's from, but that's pretty perfectly indicative of the vibe. New York/New Jersey, but fictional New York/New Jersey, no familiar/real skyline, and like the place just never got cleaned up. Mob still runs the town, streets are grimey & run-down to hell, it probably rains 300 days a year and everyone still dresses like Bugsy freakin' Siegel.
And some more Dark City goodness for the hell of it, still such a stunning-looking movie:
Embrace this feel and you'll have something different for on-screen Batman, big-time. Not just the city design, but the whole mood, cinematography, just go full-on noir this time around given it's supposedly a heavily detective-based thing.
Honestly, I wouldn't even mind a voiceover narration from Bruce. So unlikely they'd do it, but that'd be fresh for the character. Really get inside Bats' head as he's stalking rooftops trailing leads, in this Dark City type alt-reality north-east-USA art-deco-but-modern hellscape.
