I'm just here to find out what others say :)
most of Stanley Kubrick's films are leaning towards the intelligentsia..
Escape To Victory!
Mulholland Drive comes to mind, and maybe the usual suspects-at the time it was filmed there weren't many like it.
I don't know about "ever," but one that comes to mind is "Valkyrie."
From among many, I pick Jacob's Ladder.
