I came in to say that!
Sea of Love (1989)
I wouldn’t call it noir, but it has some noir-ish moments… and the requisite sex and the twist ending.
Someone to Watch Over Me (1987)
No Way Out (1987)
Jagged Edge (1985)
Third The Grifters, Blue Velvet and Blade Runner. All nice little takes and twists on the genre.
I see No Way Out has been mentioned, so…
