ATHENS — A documentary about C8 contamination in the Mid-Ohio Valley will be shown at the Athens (Ohio) International Film and Video Festival that opens Monday.

“The Devil We Know” will be shown twice at the festival, 3:30 p.m. April 14 and 3:45 p.m. April 15 at the Athena Cinema, David Colagiovanni, executive director of the film festival, said.

The documentary is about C8, also known as PFOA, that was once used to make Teflon at the DuPont Washington Works plant in Wood County, now owned and operated by the spinoff company Chemours.

A science panel created by a settlement with DuPont studied the health data from 70,000 residents of the region and found probable links to six diseases in humans. Other communities around the world have reported people and water sources contain the compound

“The Devil We Know” premiered in January at the Sundance Film Festival and was directed by Stephanie Soechtig and written by her and Mark Monroe. Soechtig’s other works include “Under the Gun” about firearms and “Tapped” about the bottled water industry.

Colagiovanni contacted the film producers and asked that the movie be shown at the festival in Athens. It’s an issue of widespread community interest here, he said.

“I wanted the movie to be shown at the film festival,” Colagiovanni said.

It’s exciting for the film festival to show “The Devil We Know,” Colagiovanni said.

“There may be a special guest here, but I don’t have that confirmed,” he said.

The movie has yet to be distributed or shown in other venues, he said. It has played at Sundance and in Denver, but this will be the first local showing, Colagiovanni said.

“This will very much be like a sneak preview,” Colagiovanni said.

The Athena Cinema is located at 20 South Court St. in Athens. Established in 1915, it opened as the Majestic Theatre, then changed to Schine’s Athena then to the Athena Cinema.

“It’s really exciting that the film will be shown locally,” said Harry Deitzler, the attorney in the original C8 class action suit against DuPont from which the settlement led to the creation of the science panel, among other things.

Deitzler also is in the movie.

“I hope people realize how significant it may be worldwide if the film gains traction,” he said.

Tickets will be available only in person at the theater, Colagiovanni said. Tickets are $4 because the show is before 5 p.m., Colagiovanni said.

The film festival will announce if the movie is sold out, he said.

The Athens Film Festival, founded in 1974, opens on Monday. Numerous domestic and international films will be shown, Colagiovanni said.

At 7 p.m. Monday at the Athena Cinema, the festival will show the world premiere of “Farmsteaders,” the first full-length documentary from Director Shaena Mallett, who graduated from Ohio University. It is about a contemporary rural family.

Other movies include “Lu Over the Wall,” “Under the Tree,” “I Am Not a Witch,” “Alaska is a Drag” and “Gravitational Field.”
