ethereal--I am reminded of
The Exiles. The scene below, near the end of the film, was apparently shot in Elysian Park. While I've driven around some of the winding streets of Silver Lake, I really don't remember if any of them are high enough over the flats to be a possibility here, but my first thought on seeing your pic is that it is a shot west from one of those streets--maybe that's Franklin in the center, Los Feliz diagonally off to the right. Just a guess... maybe it's a clip from an actual noir that someone out there in the dark will identify immediately....
