An eagle-eyed fan on Reddit posted a screen grab from Batman Vs. Superman of the Batcomputer where Bruce Wayne connected to the Oracle Network to decrypt the Lex file.
Of course, Barbara Gordon in the comics is known as the computer hacker/tech specialist behind Birds of Prey (the character is also rumored to be appearing in Supergirl).
The Oracle Easter Egg could also reference a run in with the Joker, again as in the comics, the Joker shot and paralyzed Barbara Gordon. Interestingly enough, Oracle made her first appearance in an issue of Suicide Squad, the next DCEU movie.
“Batman v Superman: Dawn of Justice” is directed by Zack Snyder starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter as Senator Finch and Tao Okamoto as Mercy Graves.
Synopsis:
Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
