I was just looking on IMDB and saw the trailer listed for the movie Seventh Son. I originally wondered if this movie is in anyway connect to the book by Orson Scott Card of the same name. Looking through what is listed on IMDB, I don't see any credit given to Card, so now I'm curious. The plot seems at least vaguely the same: Seventh son of the seventh son; 1800's setting; battling evil with magic. I don't know if there are further plot similarities, but this seems a little too obvious to be missed. What's going on here?
No relationship to the book; it's an adaptation of a different book series (The Wardstone Chronicles):
However, this doesn't mean that this other book isn't related to Card's book, somehow. That's a different discussion, though.
