Card is one of the best science fiction writers around. Why is he working on a comic book?
Why not?
Compare the box office for movies based on comic book characters against the box office of movies adapted from “fine literature” (AKA “Oscar bait”). You’ll find at least a couple of extra zeros in the gross for the superhero action flick, compared to the gross for the literary “film”.
I believe he’s a “Superman” fan.
“Adventures of Superman” is going to be a new digital anthology, with chapters coming out every week. DC solicited a wide variety of writers to contribute; it’s a standalone book, so none of the creators have to be concerned with previous continuity.
Because comic books have come a long way from being campy and unserious.
