This anthology film, Ten Minutes Older: The Trumpet, has some gems. I particularly liked the documentary segments by Werner Herzog (about a Brazilian tribe contacted by the government in 1981, apparently the last such contact in history) and Spike Lee ("We Wuz Robbed," about the 2000 election).

Jim Jarmusch's bit, with Chloe Sevigny playing "an actress" was also nice: like an acting exercise, just ten minutes of time, one person living those minutes, waiting in a trailer. Don't forget that creating such a scene, as an actor, requires observation and craft.

A director I don't know, Victor Erice, put in a nice period tone poem sent in early-40s Spain (and featuring a song in the Asturian language)

The interstitial music, a jazz combo, is also terrific (glories of the upright bass). Interstitial footage, of shimmering water, was filmed on the River Cam.
