In a well-suited tie-in for Batman v Superman: Dawn of Justice, Warner Bros. teamed with the Organization for Bats Conservation to promote National Save the Bats Week, an effort to educate the public about the flying mammals and the fungus that threatens them.

In the video below, director Zack Snyder and stars Ben Affleck and Amy Adams talk about the importance of bats, and we see volunteers construct brightly colored bat houses using scraps of wood recycled from the set of the upcoming film.

Opening March 25, 2016, Batman v Superman also stars Henry Cavill, Gal Gadot, Laurence Fishburne, Diane Lane, Jesse Eisenberg, Jeremy Irons, Holly Hunter and Scoot McNairy.
