If that's not magic, I don't know what is. The film franchise itself ranks as highest grossing book-to-film series of all time, having earned (as of this writing) $3.5 billion worldwide, beating even The Lord of the Rings film trilogy (which has grossed $2.9 billion). Rowling has sold over 325 million copies worldwide, spawning the film series, at least five video games and over 400 other Harry Potter-branded products. Harry Potter is more than everyone's favorite boy wizard - he's a cultural phenomenon of unmatched proportions.
