Around Christmastime the news came out that yes, Virginia, the new "Shazam" movie (which may or may ot have a hero in it named Captain Marvel) WILL be a part of the shared continuity of the curent slate of DC Comics' superhero movies. There had been thought that is would be separate, as "Earth S" was from the regular universes of DC superheroes before the Crisis on Infinite Earths in 1986.
