Bradley Cooper and Todd Phillips' 22 Green Production company is teaming up with Andrew Lazar and Warner Bros. to produce Ghost Army. The studio has acquired the rights to Rick Beyer and Elizabeth Sayles' non-fiction book The Ghost Army Of World War II: How One Top-Secret Unit Deceived The Enemy with Inflatable Tanks, Sound Effects, And Other Audacious Fakery, which was published in April by Princeton Architectural Press. The adaptation will also use Rick Beyer's 2013 PBS documentary Ghost Army as a source for this project.

The story follows a secret U.S. Army unit, comprised of recruits from art schools, advertising agencies and other creative businesses, who were tasked with finding ways of tricking the Nazi army into believing that the U.S. had more troops than they really did. They used everything from inflatable tanks, mixed in with actual tanks, to dummy soldiers that would be spotted by German spy planes and delivering fake radio messages for the enemy to intercept, that left them confused about where they should attack next. Their efforts were credited with saving tens of thousands of lives, and there is currently an ongoing effort to have the entire squad awarded with the Congressional Medal of Honor, after their story was kept secret for more than 40 years after the war ended. Fashion icon Bill Blass was one of the members of this unit.

While he is only confirmed to produce at this time, Deadline reports that the studio hopes Bradley Cooper will also want to star in the movie as well. After setting the box office on fire earlier this year with American Sniper, Bradley Cooper will next be seen in Adam Jones and Joy. He is also planning on starring in and directing Warner Bros.' A Star Is Born remake.
