"Two uniquely American art forms spawned in the 20th century were comic books and rock n' roll. But before that, in the early 1940s, the Captain Marvel comics became so popular that he even outsold those of Superman for several years. So, the character's publisher decided to create a spin-off hero and one of the new Captain Marvel Jr. comics' most ardent fans was a young boy named Elvis Aaron Presley. So when did he exactly come across it? No one is sure but a copy of 1947's Captain Marvel Jr. #51 is placed on the desk in the recreation of his childhood room at Memphis' Lauderdale Courts housing complex. There are the other clues: Elvis' early haircut seems very much based on that of Freddie Freeman from his late '40s period. Elvis' signature "half capes" worn on stage also seem very inspired by those worn by the teenage hero. And the insignia for Elvis' core rhythm section, the TCB band? It's a very Shazam-esque lightning logo. These all point to direct homages to the superhero he grew up loving the most. And in turn, ever since it was revealed how much Elvis loved Captain Marvel Jr., the comics themselves have returned that inspiration. In the 2000s era Teen Titans series, Captain Marvel Jr. was described as a big Elvis fan. Another famous homage took place in DC's seminal graphic novel Kingdom Come, where we get a glimpse of a future version of Captain Marvel, Jr., whom artist Alex Ross specifically designed to look just like '70s-era Elvis. He even named the character "King Shazam," as a tribute to him. So, will Jack Dylan Grazer pay homage to Elvis in Shazamǃǃ, the movie? Unknown, but if it were to happen, it would sure be in keeping with tradition."
