Sidney Kimmel Entertainment has secured film rights to Sara Pennypacker’s critically acclaimed, New York Times bestseller “Pax.”

SKE prevailed over several other companies in a highly competitive bidding race. It will develop and finance “Pax.” SKE President John Penotti and President of Production Carla Hacken made the announcement this morning.

Meaning “peace” in Latin, “Pax” tells the story of a boy separated from his pet fox, and their independent struggles to return to each other in the face of a devastating war.

Pennypacker is the author of 20 children’s books that have received numerous awards and honors, and is best known for her New York Times bestselling series “Clementine.”

Pennypacker was moved by reports of children injured, displaced and orphaned by wars around the globe and was inspired to write a novel that explores the costs of war, especially to children, through the eyes of a boy and his pet fox.

“In its short time in release, Sara’s nuanced and poignant novel has resonated with children and adults alike and we are thrilled to have the opportunity to adapt ‘Pax’ for the big screen,” Hacken said. “We look forward to having an incredible storyteller like Sara as a partner in this project.”

SKE’s next film “Demolition,” starring Jake Gyllenhaal and Naomi Watts, is set to bow on April 8. The deal was brokered by Sylvie Rabineau of RWSG Literary Agency on behalf of Steven Malk of Writers House.
