Over at The Tainted Archive, there's a story about how the famous Frank Miller graphic novel that ushered in the darker Batman might be made into a movie. It would stand apart from the new continuity established by Christopher Nolan and Christian Bale. Clint Eastwood's been mentioned as taking on the role with Zach Snyder directing.
As much as I love Batman (see my forgotten book review tomorrow), I have but one question: WHY? Didn't Snyder and company learn anything from Watchmen? It's not a slam against the well-made movie version of Watchmen, it's just that the source material--art included--is so good and vivid that we really didn't need the film version. Do we really need a film version of The Dark Knight Returns?
