I've heard whispers that the currently circulating Shazam! script features just a small number of scenes that echo Alan Moore's Miracleman stories a little too closely.
For those who aren't up to speed, Miracleman was created in the 50s as Marvelman, by lifting, pretty much wholesale, the specifics of Fawcett's Captain Marvel - who was himself, originally, a loose copy of Superman.
Alan Moore revived Miracleman in 1982, subverting his origins so radically and creating storylines so adventurous that its hard to see how they've ended up getting woven into any current Captain Marvel work.
Apparently, though, they have.
I think a clue might be, funnily enough, The Brady Bunch Movie.
I'm doing research, and should I find out any more, then I'll share it with you as soon as possible.
I'm finding it hard to even guess how Moore will react if he has been plagiarised here.
