WILTON – The Sunday Doc Film Series at the Wilton Town Hall Theater continues at 4:30 p.m. May 5 with the showing of “Lobster War.”

Admission is free, although donations are accepted.

“Lobster War” is a must-watch, award-winning feature-length documentary film about a conflict between the United States and Canada over waters that both countries have claimed since the end of the Revolutionary War. The disputed 277 square miles of sea known as the Gray Zone were traditionally fished by US lobstermen. But as the Gulf of Maine has warmed faster than nearly any other body of water on the planet, the area’s previously modest lobster population has surged. As a result, Canadians have begun to assert their sovereignty, warring with the Americans to claim the bounty.

Directed by David Abel, a Pulitzer Prize-winning reporter at The Boston Globe, and Andy Laub, an award-winning documentarian, producers of the acclaimed Discovery channel documentary “Sacred Cod.”

The Souhegan Sustainability is sponsoring engaging and informative films and programs outside its Annual Fair (this year from 10 a.m. to 4 p.m. on May 4 at the Wilton-Lyndeborough Cooperative School).
