Even though the various current DC Comics-based live-action projects operate in separate fictional worlds (movies on one side, TV shows on multiple other sides), Warner Bros. isn't going to waste an opportunity for cross-promotion. Thus new footage shown of the upcoming "Batman v Superman: Dawn of Justice" which aired during tonight's midseason finale of "Gotham" on Fox, and has already made its way online.

In the 35-second clip, a shackled Batman is confronted by Superman -- who disdainfully unmasks him. It's a quick sneak, but there's much more to come on Wednesday, with the full trailer reveal set for ABC's "Jimmy Kimmel Live," as revealed by the "Batman v Superman" Twitter account.

Directed by Zack Snyder and starring Ben Affleck, Henry Cavill and Gal Gadot in her debut appearance as Wonder Woman, "Batman v Superman: Dawn of Justice" is scheduled for release on March 25, 2016.
