As part of DC's Multiversity project, All-Star Superman team Grant Morrison and Frank Quitely will be helming a comic entitled Pax Americana, a tribute to Alan Moore's Watchmen that uses analogues to Alan Moore's characters in modern times.
In an interview with the magazine Comic Heroes, Morrison described the project as a 21st century Watchmen that used the original Charlton Comics characters. Remember, the characters of Watchmen were based on superheroes that DC acquired from Charlton in the 1980s — The Question = Rorschach, Captain Atom = Dr. Manhattan, and so on. Morrison also noted that he sees these characters not as fixed, immutable creations, but rather as icons ripe for reinvention. (Indeed, this is a sentiment he expressed to us regarding Batman.)
