Deadline says that Walden Media has acquired the film rights to Where in the World is Carmen Sandiego? from Houghton Mifflin and is developing the property as a vehicle for Jennifer Lopez to star in. Walden Media says that Lopez is only attached to produce for now. The site offered the following logline: "When the ACME agency's greatest detective Carmen Sandiego becomes the world's greatest thief, it's up to her former partner to follow her clues and track her down. Their cat-and-mouse game leads the partner to confront a greater mystery: Is Carmen really a thief or a hero? The property originated as an educational computer game before it was turned into an animated TV series." Lopez will produce with her Nuyorican Productions partners Benny Medina and Simon Fields, and Underground Films' Nick Osbourne, Trevor Engelson and Devin Andre. Walden Media CEO Michael Bostick and SVP Evan Turner are overseeing the project.
