Great question — answering as the UphillTech team:
No relationship to the book; it's an adaptation of a different book series ( The Wardstone Chronicles ): http://en.wikipedia.org/wiki/The_Seventh_Son_(film) However, this doesn't mean that this other book isn't related to Card's book, somehow. That's a different discussion, though.
