There's this whiff of a warped-hint of irony (or perhaps it be "cyclic-evolution") whereby the conceptual-path / journey of a live-action film adapted from a printed-comic book (story) further produces printed-books about the making of said live-action-film. Glorious, methinks. And Rorschach has become the de-facto poster-child for the film (heh).
