Morgan Freeman has signed on to star in action movie “Down to a Sunless Sea,” set up at Focus Features.

Focus has bought the script by David Gleeson. The logline is under wraps, but is said to be similar in tone to “Air Force One.” Producers are Bruce Cohen and Freeman’s Revelations, which is headed by Lori McCreary. CAA brokered the package deal.

Freeman starred in last year’s sci-fi hit “Lucy” with Scarlett Johansson and in “Ted 2.” He’ll be seen next year in “London Has Fallen” and the “Ben-Hur” remake.

Cohen’s producing credits include “Silver Linings Playbook,” “Milk” and “American Beauty.”

Gleeson was attached in 2013 to write a J.R.R. Tolkien biopic, “Tolkien,” for Fox Searchlight and Chernin Entertainment. Gleeson is repped by CAA and Warren Dern.
