“Harry Potter” star Daniel Radcliffe (inset) has been tapped to star in an adaptation of the book “Horns.” That’s big news here because Joe Hill , the author of the best-selling thriller, is a New Hampshire guy (and Stephen King’s son), and the book is set in the Granite State. “Horns” is about a guy who, after a night of misbehavior, wakes up with horns. Growing horns is just about the only thing that didn’t happen to Radcliffe as Harry Potter.
