Samuel L. Jackson has signed up to star in Unthinkable for Senator Entertainment.

The story centers 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.

Gregor Jordan will direct from a script by Peter Woodward and Oren Moverman.
