This looks like a very interesting movie, which may assume some degree of a Christian worldview. The official movie website writes the following about the movie:
Copperhead is unlike any Civil War movie to date. It is a film of the war at home – of a family ripped apart by war, of fathers set against sons and daughters, of a community driven to an appalling act of vengeance against a man who insists on exercising his right to free speech during wartime. A story of the violent passions and burning feuds that set ablaze the home front during the Civil War, Copperhead the Movie is also a timeless and deeply moving examination of the price of dissent, the place of the individual amidst the hysteria of wartime, and the terrible price of war – a cost measured not in dollars but in fractured families, broken loves, and men dead before their time.
Based on the extraordinary novel by Harold Frederic, who witnessed these conflicts firsthand as a small child, Copperhead tells the story of Abner Beech, a stubborn and righteous farmer of Upstate New York, who defies his neighbors and his government in the bloody and contentious autumn of 1862. The great American critic Edmund Wilson praised Frederic’s creation as a brave and singular book that “differs fundamentally from any other Civil War fiction.”
