Production on Batman v Superman: Dawn of Justice is showing no signs of slowing down, with recent reports surfacing that the crew is building a massive set in New Mexico, with shooting also slated to begin in Chicago next month. While it remains unclear when principal photography will actually be complete, a new report from Batman-on-Film claims that Warner Bros. already has a teaser trailer "ready to go."

The site's sources claim that the teaser will be attached to one of Warner Bros.' November or December releases, which could be one of four possibilities: Horrible Bosses 2 (November 26), Inherent Vice (December 12), The Hobbit: The Battle of The Five Armies (December 17) or American Sniper (December 25, in limited release). While none of these are superhero titles, if word got out that the first trailer for Batman v Superman: Dawn of Justice was attached to any one of these films, it would surely boost the opening weekend sales.

This report also claims that the teaser is "Batman heavy," meaning it focuses primarily on Ben Affleck's Dark Knight. If this is true, it would make sense for the first widely-released footage to focus on this new version of Batman, perhaps to try and sway the fans who were overly critical of Ben Affleck's casting last year.

Naturally, it hasn't been confirmed if a teaser trailer has been completed or not, but it's worth noting that production has been under way for several months, and there is likely plenty of footage that could be used for a brief tease of this highly-anticipated superhero adventure.

We'll keep you posted if we hear anything official about a teaser trailer for Batman v Superman: Dawn of Justice.
