For this series, just one film: The World (2004) directed by Jia Zhangke.
Chicago Reader's Jonathan Rosenbaum gives us his blurb: “Suggesting at different moments a backstage musical, a failed love story, a surreal comedy, and even a cartoon fantasy, this beautiful, corrosive, visionary masterpiece by Jia Zhang-ke is a frighteningly persuasive account of the current state of the planet. Set in an eerie Beijing theme park--a kind of Chinese Las Vegas, with scaled-down duplicates of the most famous global landmarks--it follows a bunch of workers as they labor, carouse, couple, and uncouple, but it's really about propping up extravagant illusions through alienated labor.”
If that doesn't temp you to seek it out, perhaps its trailer will.
