Filmmakers Michael Graziano and Ernie Park were originally inspired by the Organic School Project, a now-defunct school garden project in Chicago, and had intended to focus the film on it. Once they started production, however, they realized that there was a much larger story to be told.
If the trailer is any indication, the resulting film adopts a visually striking style as it portrays the surprisingly long and tortuous history of school food in this country.
