Samuel L. Jackson is set to star in the Gregor Jordon-directed suspense thriller "Unthinkable" for Senator Entertainment says Reuters.

In the story, penned by Peter Woodward with revisions by Orin Moverman, a major threat is posed to the U.S. 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 (Jackson) and a female FBI agent have to decide how far they will go to find the weapons.

Principal photography is scheduled to begin September 2nd in Michigan.
