USA TODAY NETWORK-Wisconsin

A documentary on one of the most controversial heroes or villains of the past few years, depending on one’s point of view, plays the next installment of the Movies That Matter series at Unitarian Universalist Fellowship of Door County.

“Citizenfour” tells the story of Edward Snowden and the National Security Agency spying scandal. In January 2013, Laura Poitras, an American documentary film director/producer who had been working for several years on a film about monitoring programs in the US that were the result of the 9/11 attacks, received an encrypted email from a stranger who called himself, “Citizen Four.” In it, he offered her inside information about illegal wiretapping practices of the NSA and other intelligence agencies.

In June 2013, accompanied by investigative journalist Glenn Greenwald and The Guardian intelligence reporter Ewen MacAskill, Poitras traveled to Hong Kong with her camera for the first meeting with the stranger, who revealed himself as Snowden, a computer professional subcontracted to work for the NSA who copied classified information showing the breadth and depth of the agency’s spying. Snowden leaked the information to various sources, after which he was charged by the Department of Justice and fled the country.

Poitras directed the subsequent movie, which won the 2015 Academy Award for Best Documentary Feature.

The Movies That Matter series is designed to examine a wide range of issues. Screenings are held on the third Tuesday of every month, with discussion following the movie. Admission is free, although donations are appreciated, and the public is welcome.

“Citizenfour” plays for the Movies That Matter series at 4:30 p.m. June 21 at Unitarian Universalist Fellowship, in the the Shops at Green Gables, 10341 Wisconsin 42, Ephraim. For more information, call 920-854-7559 or go to www.uufdc.org.
