I could recommend, "Our Daily Bread".
Write up as seen on youtube page:
"OUR DAILY BREAD reveals the little-known world of high-tech agriculture. In a series of visually stunning, continuously tracking, wide-screen images that seem right out of a science-fiction movie, we see the places where food is cultivated and processed: surreal landscapes optimized for agricultural machinery, clean rooms in cool industrial buildings designed for maximum efficiency, and elaborate machines that operate on a 'disassembly line' basis.
Dispensing entirely with explanatory commentary or 'talking-head' interviews, OUR DAILY BREAD unfolds on the screen like a disturbing dream: an endlessly fascinating flow of images, an insistent gaze, accompanied only by the persistent industrial soundtrack—whirring, clattering, booming, slurping—of the ingenious marvels of mechanization employed by agri-business."
Also, "Control Room".
