A History of Violence is an adaptation of the graphic novel by John Wagner and Vince Locke. From the movie site you can even download the first installment of the story in PDF format, though it may “spoil” the movie for you.
It looks like DC is going to re-release the graphic novel with a new movie cover.
The film features Ed Harris (of one of my favorite films, The Abyss) and orc-murdering peacenik Viggo Mortensen.
