DC Comics has officially confirmed that Superman ’78 and Batman ’89s universes are one and the same. In Dark Crisis: Big Bang #1 by DC Comics, the world where Michael Keaton‘s Batman and Christopher Reeve‘s Superman operates are revealed to be Earth-789, as the two heroes exist in the same timeline. The recent reveal sets up a potential future comic crossover while also confirming important facts about each world.
In Dark Crisis: Big Bang by Mark Waid, Dan Jurgens, Norm Rapmund, and Federico Blee from DC Comics, The Flash takes a journey across the Infinite Earths. By the issue’s end, many Earths get new designations, with the most notable one being Earth-789. First, DC describes the world where “Superman and Supergirl are Earth’s only powered heroes” and where “Batman’s parents [were] killed by the Joker.” The listing then directly refers to both Superman ’78 and Batman ’89 being part of Earth-789, confirming that Michael Keaton‘s Batman and Christopher Reeve‘s Superman exist in the same world.
The worlds of Michael Keaton‘s Batman and Christopher Reeve‘s Superman have long been theorized to be connected – with a proposed film crossover in Tim Burton‘s Batman being pitched and rejected. DC Comics has even hinted in the recent Superman ‘78 miniseries, which continued the adventures of Reeve‘s Man of Steel, that Keaton existed in his universe, with several easter eggs alluding to The Dark Knight’s presence in the world. Now, DC Comics is officially confirming the two characters are part of the same reality, as Earth-789 is named.
While viewers and readers have long-suspected Keaton‘s Batman and Reeve‘s Superman took place in the same world, the reveal of Earth-789 means a crossover in the comics is finally possible. With the success of Superman ’78 and Batman ’89, with both comic series’ brilliantly continuing the adventures of the film versions of the heroes in the pages of DC Comics, the confirmation they are from the same reality hopefully means they will star in their own World’s Finest-esque comic soon. Seeing Keaton‘s Batman and Reeve‘s Superman interact would be so much fun.
Earth-789 is a fitting name for Michael Keaton‘s Batman and Christopher Reeve‘s Superman’s joint universe, as its number combines their eras. Hopefully, the official designation and confirmation that Batman ’89 and Superman ’78 exist in the same world will set up their next stories in the pages of DC Comics. Seeing their universe expand together decades after they debuted would be well worth the wait.
