I'm a Stanley Kubrick fan, but the only film of his that I saw in the theater was Eyes Wide Shut. Which led me to wonder -- what were the trailers for his movies like? Short answer: friggin' nuts. Enjoy. (I'll start with my two favorites, then go in reverse chronological order.)
A Clockwork Orange (1971)
Do not watch if you're prone to seizures.
Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)
Perhaps a precursor to the A Clockwork Orange trailer, with its constant cuts.
Eyes Wide Shut (1999)
A hell of a trailer for a hell of a movie.
Full Metal Jacket (1987)
"Sir, does this mean that Ann-Margaret is not coming?"
The Shining (1980)
I think this is the real trailer, but the number of fan trailers and spoofs makes it hard to tell.
Barry Lyndon (1975)
This is a sort of promotional catalog of good movie reviews read in voice-over. Perhaps a response to the A Clockwork Orange trailer? "A masterpiece. Monumental, a perfect film of epic size." I know a lot of fans would say its size is perhaps too epic.
2001: A Space Odyssey (1968)
Love the title card at the end: "The most dazzling visual happenings in the history of the motion picture! -Time Magazine"
How did they ever make a movie out of Lolita?
"Unlikely ever to be surpassed in the magnitude of production." Pro tip: don't ever claim unsurpassability in your trailer.
Paths of Glory (1957)
Whoa, bad-ass. Way badder-ass than the Spartacus trailer.
The Killing (1956)
"Daring hold-up nets $2,000,000!"
