I dunno. I'm trying to figure out what I can cover and what is too dumb or commonplace. Any reasonably serious film fan knows about expressionism and its impact on film, but how much do people really know? You can draw a pretty clear line from, say, The Cabinet of Dr. Caligari all the way to Sin City. German expressionism has always been around (heck, it's even been popular since its inception in the 20s, in one form or another), but do people actually know much about it? Or care? I mean, it's pretty rare for a visual style in films to be popular after 80 years. Sure, certain camera shots and tricks will always be popular, but I'm not sure if I can think of a complete style that's had the staying power of expressionism. It's very rare for anything to be popular for that long in any art form.
What brought this on was watching Twin Peaks Gold Box. . .and noticing that there are several pretty blatant instances of expressionism-inspired shots. And I don't mean second or third gen inspired: I mean shots that are lit to even appear sepia in tone. It's kind of fucked up to be watching something relatively recent, and then to see a shot that looks like one Murnau framed himself. Spiffy, spiffy shit.
