The Real Story:
In 1859, American settler Lyman Cutlar shoots Irishman Charles Griffin's pig, but since this happened on disputed territory on the American/Canadian border, the armies waded in. However, war was averted, and the only casualty was the pig.
A surreal black comedy about a diplomatic squabble, that doubles as a reminder to today's governments that you don't always need to shoot first and ask questions later.
David O. Russell.
