Really enjoyed this film, with wonderful performances by Jiang Wen, Chow Yun-fat, and Ge You (and the supporting cast as well).
I've read there's a political subtext which is expressed through visual/spoken jokes, but which I wasn't able to catch, not being a native speaker/familiar with Mainland politics. Does anyone know of a good article discussing them, or want to try explaining what they were?
