On Friday, Cooper agreed to star in and produce American Blood, a thriller based on 50 pages of a Ben Sanders crime novel that has yet to be published.
Cooper will play Marshall Grade, an former NYPD officer who becomes a mob informant. He's in the witness protection program when he's drawn into a missing-persons investigation.
Andrew Sodroski will adapt Sanders' book, which doesn't hit shelves until the fall of 2015.
