Tom Hanks playes a newbie making his first trans-Atlantic crossing as commander of a destroyer escorting a convoy through Nazi submarine invested waters in a stunning new trailer for upcoming movie “Greyhound.”

“We’ll bring hell down from on high,” he avows as the subs, hunting in a “wolf pack,” close in.

Hanks not only stars in the film as Commander Ernest Krause, USN, but he also wrote the screenplay. Up and coming director Aaron Schneider helms the film.

The picture also stars Stephen Graham, Rob Morgan, and Elisabeth Shue.

The only thing more dangerous than the front lines was the fight to get there, according to a movie synopsis. In the early days of WWII, an international convoy of 37 Allied ships, led by captain Ernest Krause in his first command of a U.S. destroyer faces off against attacking submarines.

The movie is based on a C.S. Forester’s novel “The Good Shepherd.” Krause, a career officer who is finally given command of a destroyer, the USS Keeling, and assigned to convoy duty.

His ship, code name “Greyhound,” must fight off attacking Nazi submarines as the convoy dashes across the Atlantic from the United States to Great Britain during World War II.

Hanks, of course, starred in the classic 1998 World War II movie, “Saving Private Ryan,” and his latest effort shares some common themes.

Krause is an “everyman” who puts aside his personal life and steps into harm’s way in order to do his duty for his country.

As the fictional Capt. John Miller in “Ryan,” Hanks must take his men behind enemy lines to find Private James Ryan, the last son alive from a family of brothers who went off to war.

Despite his military prowess, Miller is a school teacher in his private life and shares many of the same fears and doubts as his men.

Krause is also the prototypical hero; he must battle his own self-doubts and personal demons to be an effective leader, despite huge responsibility for his men and ships.

“Greyhound” is set in the North Atlantic in 1942, a time when the war was very much in doubt and Germany controlled much of Europe. The convoys were Britain’s only lifeline for food, supplies and military equipment.

Many of the shipboard scenes were shot on the USS Kidd, a World War II-era Fletcher-class destroyer that is now a floating museum in Baton Rouge, Louisiana. The rest of the action involves some pretty high concept CGI for realism.

The scenes at sea make for pretty rough going. Anyone who suffers from motion sickness better medicate before seeing the picture.

The Battle of the Atlantic was the longest continuous military campaign in World War II, running from 1939 to the defeat of Nazi Germany in 1945.

German U-boats, hunting as a wolf pack, would spread out in a long line across the projected course of a convoy. Upon sighting a target, they would come together to attack at once in an effort to overwhelm any escorting warships.

The film is being produced by Playtone’s Gary Goetzman and Hanks. FilmNation Entertainment’s Aaron Ryder, Playtone’s Steven Shareshian and David Coatsworth are executive producers.

FilmNation sold worldwide rights to Sony Pictures Worldwide Acquisitions, which is financing in association with Bron Creative, Sycamore Pictures and Zhengfu Pictures, according to The Wrap.

The film’s release date, originally reported to be in April, is now set for June 12.
