Batman: The Dark Knight Returns is based on the Frank Miller graphic novel by the same name (actually four books, starting with The Dark Knight Returns), which is set in the same version of Gotham as Frank Miller's Batman: Year One.
Some time back we reported that Alan Moore, famed creator of The Watchmen and V for Vendetta, and Frank Miller, father of the Dark Knight graphic novel, had gotten into a heated exchange of words over the Occupy movement.
Last summer, the upcoming Daredevil adaptation recruited Brad Caleb Kane, the writer-producer of Fringe, to start on the screenplay. Now they appear to have started over with a new writer, David James Kelly.
Unless you're living in a cave, you just can't avoid reports of the OccupyWallStreet (OWS) movement. It's also inflamed two major graphic novels superstars: Alan Moore (V for Vendetta, Watchmen), and Frank Miller (The Dark Knight Returns, 300, Sin City).
