I haven't. Here's somebody's ranking of all of them. There are 13.
Up until last night, I'd seen "Dr. Strangelove," "Lolita," "The Shining," "Clockwork Orange," "Barry Lyndon," "Paths of Glory," "2001," "Full Metal Jacket," and "Eyes Wide Shut." (Named in the order that I like them.)
Yeah, I'd never seen "Spartacus," and I still haven't. Unsurprisingly, I'd never seen "Killer's Kiss" or "Fear and Desire."
