I went to see Manfred Kirchheimer's new documentary Canners yesterday. Here's the trailer for it. You can catch it through Thursday at the newish Metrograph cinema, on Ludlow Street (if you can brave the weather). The Metrograph has a bit of an affected vibe going on, but the programming is great, and I've got used to the indulgence of reserving seats. I'll take their airs.
Kirchheimer's classic Stations of the Elevated (1981) was screened in a retrospective I saw fairly recently. Here's the trailer for that one too.
