At first glance, it looks as if David Sandberg is really going to give fans an inside look at his Shazam film but halfway down the page, it becomes clear that Sandberg has played a hilarious joke. But perhaps there's a bit of truth in this madness?
While it's unlikely that Superman's going to be playing dirty tricks on Billy Batson, perhaps he'll have some other role to play in the film. There have been rumors circulating for months that Shazam, Black Adam and Superman's post-Justice League cinematic adventures would all be connected in some fashion so don't be surprised if Henry Cavill actually shows up in the film.
Of course, WB and Sandberg actually need to cast someone as Billy and/or Shazam so unless things are progressing behind-the-scenes, DC's Captain Marvel movie still looks to be a ways off.
