...or 39 of them. Spielberg's DreamWorks has acquired the rights to The 39 Clues, what Variety describes as "a multiplatform adventure series." As yet The 39 Clues is a 10-book series, the first of which, The Maze of Bones, will be released on September 9th of this year by Scholastic. The "multiplatform" part seems to include a set of collectible cards, an online game where young readers can try to solve a mystery for a $10,000 grand prize, and obviously, the Spielberg flick. Which, according to DreamWorks' co-chair, may not be the only one coming to the big screen. "There is enough material here for three or four movies," Stacey Snider told Variety, adding, "Steven is very involved and passionate. This excites me as an executive but also as a mother. It is an educational, challenging interactive experience that hits kids where they live." Ouch.
