Even as fans and creators attempt to unravel the hidden links between "Watchmen" and DC Comics' new Rebirth continuity, an eagle-eyed viewer has uncovered a nod to the influential Alan Moore/Dave Gibbons series in another place: "Batman v Superman: Dawn of Justice."
One Redditor discovered a collected edition of the seminal 1986 comic, with the telltale yellow type on the spine, amid the stacks of books on Lois Lane's shelves. You can see it in the image below, on the right, beneath the lamp.
One could probably make a case for "Watchmen" and "Batman v Superman" sharing themes involving superheroes, power and misplaced trust. However, it seems more likely the Easter egg is simply a nod to director Zack Snyder's 2009 adaptation of "Watchmen," which starred, among others, Jeffrey Dean Morgan and Patrick Wilson. They of course all appeared in "Batman v Superman" -- Morgan as Bruce Wayne's father Thomas Wayne, and Wilson as the voice of the President of the United States.
Meanwhile, DC Comics is preparing to explore how the "Watchmen" characters have manipulated current continuity, something first hinted at last year in "DC Universe: Rebirth" #1, most notably with the discovery of the bloody smiley-face in the Batcave. Since then, numerous "Watchmen" clues have been scattered throughout DC titles.
With "Batman v Superman" available now on Blu-ray, it's possible more "Watchmen" nods will be uncovered. If not, there's always Snyder's "Justice League," starring Ben Affleck, Henry Cavill, Gal Gadot, Jason Momoa, Ezra Miller and Ray Fisher. The film opens Nov. 17.
