Imax will debut Warner Bros.’ first full-length trailer for “Batman v Superman: Dawn of Justice” next Monday in some of its theaters.

Director Zack Snyder confirmed the news via a tweet and trailer tease late Wednesday.

The Celebration Cinema theater in Grand Rapids, Mich., disclosed the April 20 event as “Batman vs Superman Imax Trailer Event.” The running time is 15 minutes.

Warner Bros. and Imax had no comment. The studio had been planning on a wide release of the trailer for “Batman v Superman” attached to the “Mad Max: Fury Road,” which opens May 15. An earlier release would not only allow WB to attach it to Disney’s “The Avengers” on May 1, but also give the studio a chance to show off footage to exhibitors at next week’s CinemaCon confab in Las Vegas.

The first tease for “Batman v. Superman” was unveiled last year at Comic-Con, a year after the project was announced as a sequel to 2013’s “Man of Steel.”

Snyder is directing from Chris Terrio’s script, from a story by Snyder and David S. Goyer. The cast includes Henry Cavill, Ben Affleck, Gal Gadot, Amy Adams, Diane Lane, Laurence Fishburne, Jesse Eisenberg and Jeremy Irons.

“Batman v. Superman” is scheduled for release on March 25, 2016.
