Jason Hall penned the script for "Sniper" about a Navy SEAL recounting his military career that included more than 150 confirmed kills. Film is based on the book "American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History" by Chris Kyle, Scott McEwan and Jim DeFelice.
Eastwood is in production on the adaptation of "Jersey Boys" and would jump to "American Sniper" once the musical finishes filming.
He is repped by Leonard Hirshan.
