The DC comics character Shazam, aka Captain Marvel, is the alter ego of a boy named Billy Batson.
Batson can transform into a superhero by saying the word "Shazam." Black Adam is Shazam's arch nemesis, reported Variety.
While Darren Lemke is set to pen the script of the superhero film, New Line Cinema has not yet named a writer or director for the spin-off.
