Samuel L. Jackson thriller “Unthinkable” with Gregor Jordan (“The Informers”) attached to direct is set for production Sept. 2 in Michigan.

The film’s plot focuses on a major threat to the United States when the locations of three nuclear devices are shrouded in secrecy by a single terrorist. With only two days before they are deployed, a black-ops interrogator and a female FBI agent have to decide how far they will go to find them.

Jordan recently completed production on “The Informers,” starring Kim Basinger, Billy Bob Thornton, Winona Ryder and Mickey Rourke. That film will be released later this year.
