Tom Hanks’

new World War II film

offers a dramatized account

of the Battle of the Atlantic.


Is Greyhound based on a true story?

In short, no. As the film’s trailer states, Greyhound 

is “inspired by,” rather than directly based on, actual events.

Hanks, who stars as United States Navy Commander Ernest Krause,

adapted the screenplay from C. S. Forester’s 1955 novel, The Good Shepherd 

(not to be confused with the 2006 film The Good Shepherd about the founding of the CIA).

Though fictional, the Forester book is deeply researched

and noted for its accurate depiction of naval warfare.
