King Corn is a feature documentary film released in October 2007 following college friends Ian Cheney and Curtis Ellis as they move from Boston to Greene, Iowa to grow and farm an acre of corn. In the process, Cheney and Ellis examine the role that the increasing production of corn has for American society.
The film shows how the industrialization of corn has all but eliminated the family farm, which is being replaced by larger and larger industrial farms. This trend reflects a larger industrialization of the North American food system, whereby, as was outlined in the film, decisions relating to what crops are grown, and how they are grown, are based more on economic considerations than their ramifications on the environment or the population. This is demonstrated in the film by the production of high fructose corn syrup, an ingredient found in many cheap food products, such as fast food.
