The licensing opportunities alone boggle the mind.

Steven Spielberg's DreamWorks Studios have acquired the film rights to The 39 Clues, a mystery series/online game that Scholastic Books is debuting in September.

The 39 Clues is a planned 10-book series about a powerful, mysterious family living in upstate New York. The first installment, The Maze of Bones, was written by Rick Riordan, author of the best-selling The Lightning Thief, and Jude Watson and Gordon Korman have signed on to write future volumes. The series will also feature a set of 355 collectible cards, and Spielberg himself says says he's hoping to direct the film adaptation.
