I like Stanley Kubrick's films too. "The Shining" is one of my favorite films, and perhaps my favorite film within the Horror/Thriller genre..."Dr. Strangelove" was another one I remember liking quite a bit, although I saw it a while back in a political science class and don't remember much of it. "Full Metal Jacket" is fantastic blend of dark comedy and drama, set against the backdrop of the Vietnam War (with an interesting depiction of urban warfare, rather than the more traditional rendering of the war as a conflict set in the jungle). "Eyes Wide Shut" was another good one, I remember catching that one on TV late one night after getting stoned and enjoyed the film's weird psychosexual themes and the way the movie's structure allowed the viewer to draw some of their own conclusions about what was happening in the plot.
Didn't much care for "A Clockwork Orange", either the book by Anthony Burgess or Kubrick's film.
"2001" I saw waaaaaay back, when I was still in elementary school, and remember almost nothing from the film except the part with the monkeys and the monolith. I've been fascinated by prehistory ever since reading National Geographic's "Dawn of Humans" series and a couple anthropological books on the topic, and that's probably one of the most famous cinematic depictions of prehistory.
In one of the Dawn of Humans issues an archaeologist was discussing a potential ceremonial altar he had unearthed at a
site in Germany that dated back to almost half a million years old (associated with the archaic human species
H. erectus), and as I was reading about it I just imagined the monolith in the background as some ancient European cavepeople fashioned bone or rocks or whatever they were doing back then, LOL. That scene had a big effect on me!
