Walden Media has acquired feature rights to young adult novel “Simon Bloom, The Gravity Keeper” and set it up with Larger Than Life and The Gotham Group.

Adam F. Goldberg, who also wrote “Atlantis 7” for Walden, has been tapped to pen the adaptation.

Story centers on an uptight science teacher who stumbles upon a magical book that gives him unlimited control over the laws of physics. With his newly acquired abilities, he must band together with his wife and kids to protect their small town and ultimately the world from evil forces in search of the book and its powers.

The novel “Gravity Keeper” was written by Michael Reisman and published by Walden Pond Press, Walden Media’s children’s book imprint with HarperCollins. Project had been set up at Universal in 2007.

Goldberg’s worked on “Fanboys” and “How to Train Your Dragon.”

Walden’s third “Narnia” pic, “Voyage of the Dawn Treader” is currently showing and it’s in production on “Journey 2: The Mysterious Island.” The production company has a first-look deal at Fox.
