Bradley Cooper is attached to star in Atlantic Wall, a World War II drama that has Gavin O'Connor (The Accountant) set to direct.
Imperative Entertainment is behind the project, which has a script by Zach Dean.
According to the company, the story tracks a lone American paratrooper stranded behind enemy lines just days before D-Day, tasked with delivering intelligence critical to the outcome of the war and compelled to fulfill a promise to protect the young son of a murdered ally.
Cooper is also coming on board as an executive producer alongside partner Todd Phillips under their banner Joint Effort.
Cooper last appeared in Phillips' War Dogs and is prepping to direct and star in Warners' remake of A Star Is Born.
