UNITY — Camden International Film Festival Selects and Unity College will present a free screening of the award-winning documentary film, “King Corn,” at 6 p.m. Thursday at the Unity College Center for Performing Arts, 42 Depot St.

The film’s co-creator and FoodCorps founder, Curt Ellis, will be present at the event for Q&A after the screening.

“King Corn” is a feature documentary about two friends, one acre of corn and the subsidized crop that drives our fast-food nation. In the film, Ian Cheney and Curt Ellis, best friends from college on the east coast, move to the heartland to learn from where their food comes.

With the help of friendly neighbors, genetically modified seeds and powerful herbicides, they plant and grow a bumper crop of America’s most-productive, most-subsidized grain on one acre of Iowa soil. But when they try to follow their pile of corn into the food system, what they find raises troubling questions about how we eat — and how we farm.

Presented in partnership with CIFF Selects. The festival, based in Maine, is recognized as one of the top 25 film festivals in the world for documentary films and filmmakers.
