Back in the day, there was a Super Hero from the Fawcett Comics', Whiz Comics series called Shazam. Lesser known, not as popular as the other super heroes in the D.C. camp or Marvel camp, but enough to get it's own TV show.
Back in the mid 70's CBS aired a TV show called "Shazam" that ran on Saturday mornings.
Shazam is essentially "Captain Marvel" and is the story of Billy Batson, a teenage boy who can transform into the superhero by speaking the magic word "Shazam!"
It was a hokey show at the time and now it's going to hit the big screen. It looks pretty fun. Check it out.
