Walter Salles (“The Motorcycle Diaries”) is in talks to helm the conservation-themed drama “Our Wild Life” for New Line.

Story is based on the true life and work of Dame Daphne Sheldrick, the leading animal conservationist in Kenya, who has devoted her life to preventing elephant extinction by endeavoring to save baby elephants left orphaned by war, poaching and culling. Jeff Stockwell (“Bridge to Terabithia”) penned the screenplay.

Cathy Schulman and Peter Guber are producing through their Mandalay Pictures banner.

Schulman began working on the project after watching a “60 Minutes” profile on Sheldrick. She and Guber flew to Africa to meet with the conservationist and began working on what she hopes will be a four-quadrant family film.

Project was formerly known as “Peaceable Kingdom” and “Elephant Orphanage” and had Nick Cassavetes attached to direct. He sued New Line last year for fraud and breach of contract after he was dismissed from the helming gig.

Salles’ directing credits include “Central Station,” “Dark Water” and “Linha de Passe.”

New Line exec Merideth Finn originated the project.
