Sometimes setting a Google Alert pays off.
It seems to have started with a post on Reddit, one that was denied on Twitter, but built upon by an interview on MTV and now the future of the Shazam! hero and related characters in the movies appears to be some thing like this:
Black Adam, played by Dwayne Johnson, is definitely going to appear in movies.
Black Adam will probably have his own stand-alone movie.
Black Adam might face Superman in a movie.
Black Adam might face Superman in "Man of Steel 2."
The "Shazam!" movie might be "off the table," but might still happen, depending on how you interpret the anonymous sources and Dwayne Johnson's interviews.
Captain Marvel or Shazam (whichever version of the hero they decide to use) might or might not appear in anything currently scheduled.
Billy Batson might appear as an "Easter Egg" in something.
As a fan of the Big Red Cheese, I have been hoping for not just a Captain Marvel movie, but a GOOD Captain Marvel movie since one was first announced back in 2003. However, from what little I have read of the scripts that have been written, seen what has been done with the character in the comics, and what I have experienced of what happens to superheroes in movies, it is likely that the concept of the character will be used as a jumping-off point rather than the material of the character be adapted into a good movie.
If that is the case, I won't mind if Black Adam gets all the press and screen time. But maybe, just maybe, someone will figure out a way to handle the character as he deserves. Something like the purity of Captain America with the sense of fun of Ant Man and the youthful enthusiasm of the latest Spider-Man. I know those are all Marvel characters, but it would be a breath of fresh air to bring that sort of stuff into the DC Cinematic Universe.
One thing is pretty much certain: If and when he does come to the big screen, Billy Bsatson/Captain Marvel will be a boy who transforms into a grown-up superhero, but keeps his own mind. That has been the standard interpretation since Roy Thomas wrote "Shazam! A New Beginning" in 1986, and it has stuck. I liked the original concept, that the boy and the hero were two distinct personalities with shared memories, but that is just too confusing for today's audiences.
