Or maybe not. Maybe this list of potential titles the studio registered through brand protection firm MarkMonitor is simply covering its bases for the all-out assault of merchandising and tie-in products/stories/whatnots. But domain name registrations frequently give away the title game for big sequels, as was the case fairly recently on Skyfall.
According to Fusible, Warner Bros. has registered a smorgasbord of applicable titles including:
Man of Steel: Battle the Knight
Man of Steel: Black of Knight
Man of Steel: Beyond Darkness
Man of Steel: Knight Falls
Man of Steel: Darkness Falls
Man of Steel: The Blackest Hour
Man of Steel: The Darkness Within
Man of Steel: Shadow of the Night
Additionally, the studio has registered abbreviated versions such as The Blackest Night and Battle of the Knight.
These are pretty clunky, and we'd wager that none of them will actually end up being the title of this sequel/DC team-up, but they also could provide a little insight on the direction of the World's Finest tale. For one thing, the presence of Man of Steel in the possible titles should assuage the fears of anyone worried that Superman would be crowded out of his own sequel. Anyone who felt that this summer's super-reboot was a grim, cynical slog won't be reassured by all this talk of darkness and blackness, though.
With David S. Goyer still hard at work on the screenplay, Snyder and company are deep in pre-production, preparing to kick off principal photography in Detroit, Michigan early next year.
In addition to Cavill and Affleck as DC's two biggest heroes, Batman vs. Superman: Man of Steel: The Darkness Within the Blackest Knight will also star Man of Steel players Amy Adams, Laurence Fishburne, and Diane Lane.
Recently, Olga Kurylenko, Gal Gadot, and Elodie Yung all tested for a lead female role that may or may not be Wonder Woman. Adam Driver, meanwhile, was rumored to be the frontrunner to play Nightwing, but the actor himself has shrugged off the story.
Superman and Batman will rumble in theaters on July 17, 2015.
