Bradley Cooper is apparently in talks to star in the spy thriller Dark Invasion.
The Oscar-nominated Silver Linings Playbook actor will take the lead role in Warner Bros' big-screen adaptation of Howard Blum's book, which he will also produce, reported Deadline.
The 38-year-old is attached to play NYPD Captain Tom Tunney, considered to be the CIA's first head of homeland security.
Set in 1915 America during World War I, the book - which will be released in the US on September 11 - follows Tunney, who is given the task of creating a team of agents to find and take German spies down.
Bradley, who has also been nominated for a Bafta for his performance in David O Russell's drama, will next star alongside Ryan Gosling and Eva Mendes in Derek Cianfrance's generational drama A Place Beyond The Pines before reprising his role as Phil Wenneck in The Hangover Part III.
