Warner Bros has acquired rights to the memoir by onetime kidnapped American aid worker Jessica Buchanan, with the idea of making a dramatic feature film that could be the next project for Clint Eastwood.

The studio and Eastwood just teamed on another true-life pic, Sully, which has made $167.2 million at the global box office since its September 9 bow and is setting up for an awards-season run. That success came after they teamed on the hit American Sniper a year ago.

Buchanan’s memoir Impossible Odds — penned by Buchanan, her husband Erik Landemalm and Anthony Flacco — tells the true story of Buchanan, who was working as an aid worker in Somalia in October 2011 when she was captured and held in the desert for 93 days until her eventual rescue by SEAL Team 6. Brian Helgeland is writing the screenplay.
