Christopher Nolan may be done with Batman now that “The Dark Knight Rises” is in theaters, but he’s far from finished with comic book heroes from the DC universe.

Coming next June is “Man of Steel,” produced by Nolan, but directed by Zack Snyder (“Dawn of the Dead,” “Watchmen”). For longtime fans who were disappointed by 2006’s “Superman Return,” the teaser for “Man of Steel” provides just a glimpse at the serious tone the next Superman film is going to take.
