The release of the new SHAZAM movie next spring brings the whole SHAZAM (and original Captain Marvel) mythos to the wide attention of the non-comic-book-reading general public for the first time in decades. The last time that the general public was exposed to SHAZAM on such a wide scale was during the 1970s, when the franchise had a live-action Saturday morning program (made by Filmation) on national network television from 1974-1977.
The 1970s Filmation SHAZAM TV series probably departs from the canonical Fawcett/DC comic book SHAZAM mythos the most. Among the differences:
1. Billy Batson is not a prepubescent child, but a 19-year-old young adult, with the education level, life experience, and sophistication expected of a reasonably intelligent young person of that age.
2. Instead of being based in Fawcett City, Billy travels the Western U.S. (mostly Southern California) aboard a recreational vehicle with an older gentleman called "Mentor," who undoubtedly draws inspiration from Uncle Dudley.
3. Billy is the only known Marvel - no Mary, Freddy, Lieutenants, etc.
4. Billy receives his power directly from the six Elders (Solomon, Hercules, Atlas, Zeus, Achilles, Mercury). There is no wizard Shazam, but Billy regularly consults with the Elders through a mystical/electronic device (called the "Eternaphone") built into the RV.
5. There are no supervillains; Captain Marvel typically rescues people from natural disasters or dangerous situations caused by their own poor choices.
6. Captain Marvel is clearly a mature adult man and separate persona from Billy Batson.
This was the version of SHAZAM to which I was first exposed, and the canonical comic book version was something I discovered later after I began reading comics. Anyone born after the 1970s would likely not recognize this version of SHAZAM, but it is interesting to look back at it and compare it with newer interpretations.
