Batman v. Superman: Dawn of Justice director Zack Snyder tweeted a teaser for a teaser trailer, which will premiere in select IMAX theaters on Monday.

The 21 second clip shows shadowy views of Superman and Batman’s costumes, followed by the combined logo.

The movie will release March 25, 2016.

Snyder recently used Twitter to share an image of Aquaman, who will also appear in the movie (see "First Look at Aquaman").
