Elle Fanning (We Bought a Zoo, Super 8) will star in Olive's Ocean, adapted from the 2004 Newbury Honor novel by Kevin Henkes, Deadline.com reported. Christina Hammonds Reed will write the screenplay. Donald Rosenfeld, who optioned the book, will produce with Andreas Roald and Celestia Fox.
The project's genesis came from Rosenfeld's experience with Elle's sister, Dakota, during the filming of Effie: "While on set, Rosenfeld asked her sister Elle what her favorite book was, and when she answered Olive's Ocean, that started the process."
