“Lobster War: The Fight Over the World’s Richest Fishing Grounds” will be screened at the Strand Theatre in Rockland on Sunday, January 13, at 3 p.m. and at Lincoln Theater in Damariscotta on Thursday, January 17, at 2 and 7 p.m.

“Lobster War” is about a climate-fueled 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 U.S. 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.

The film is directed by David Abel, a Pulitzer Prize-winning reporter at The Boston Globe, and Andy Laub, an award-winning documentarian. Abel and Laub also produced and directed the Discovery Channel documentary “Sacred Cod.” “Lobster War” won the 2018 award for Best New England Film at the Mystic Film Festival and was runner-up for the Grand Prize for Best Feature Film at the 2018 International Maritime Film Festival.

Tickets for the Strand screening are $7.50. Tickets for the Lincoln Theater show are $8, available starting one hour before showtime.
