For those of us comic book buffs, we might have had to take a deep breath before explaining to non buffs what just happened this year, with both Captain Marvel and Shazam hitting the theaters when they are technically the same person.
In the late 30’s Captain Marvel made his debut and was owned by Whiz Comics and Fawcett Publications. It was a competitor’s response to Superman and the comics did very well.
According to Wikipedia:
HE IS THE ALTER EGO OF BILLY BATSON, A BOY WHO, BY SPEAKING THE MAGIC WORD “SHAZAM” (ACRONYM OF SIX “IMMORTAL ELDERS”: SOLOMON, HERCULES, ATLAS, ZEUS, ACHILLES, AND MERCURY), CAN TRANSFORM HIMSELF INTO A COSTUMED ADULT WITH THE POWERS OF SUPERHUMAN STRENGTH, SPEED, FLIGHT AND OTHER ABILITIES.
But after a series of disputes and lawsuits, Captain Marvel was semi-retired until DC Comics/National in the 1970s licensed Captain Marvel and then purchased him in the 1990s.
Marvel Comics, however, was able to secure the trademark of Captain Marvel, so DC Comics couldn’t use the Captain Marvel name anymore. So in renaming the superhero, DC Comics combined the electrical powers of Captain Marvel with the word used by the wizard’s spell, Shazam!
So rather than Billy Batson becoming Captain Marvel when he cries “Shazam”, he simply becomes, Shazam.
Shazam hits theaters April 5, 2019.
