This looks exactly the way I saw it in my head when I first read the book 25+ years ago. Crash (the real Crash, not the shitty Oscar-bait Los Angeles navel-gazing one) didn’t really land for me even though I’m a Cronenberg fan, and other Ballard novels are likely unfilmable.
The Crystal World and The Drowned World might be doable in animation, but they’d be commercially unviable headfucks.
ETA: Tanino Liberatore Crash. Just throwing that out there. It would be perfect.
ETA: Tarkovsky or German could do them if they weren’t both dead. If anyone reading this hasn’t seen Solaris, Stalker, or Hard To Be A God, rectify that shit ASAP.
