Gary Oldman plays British politician Winston Churchill in the first trailer for Focus Features’ “Darkest Hour,” which explores Churchill’s attempt to rally a nation while Nazis roll across Western Europe.

The trailer begins with the appointment of Churchill as Prime Minister in 1940. Soon, it becomes clear that Churchill must face one of his most difficult decisions yet: negotiate a peace treaty with Nazi Germany, or fight against them.

As a threat is imminent, Churchill makes a decision that the public, and the King, did not see coming.

“You cannot reason with a tiger when your head is in its mouth!” Churchill tells his advisers.

One of Churchill’s greatest speeches, which served as a great inspiration for the British, is included in the trailer as well.

“We shall defend our island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender,” he says.

Directed by Joe Wright (“Atonement”), the film also stars Kristin Scott Thomas, Lily James, Stephen Dillane, Ronald Pickup, and Ben Mendelsohn. It was written by Anthony McCarten (“The Theory of Everything”).

“Darkest Hour” will be released in select cities on Nov. 22.

March 17: "Beauty and the Beast"

Yes, Disney is producing a lot of live-action version of their original IP, but after the success of "The Jungle Book" last year, we can't wait for this one. Also, Emma Watson is the perfect Belle and, based on what we've seen from trailers, it will be magical.
Disney
April 14: "The Fate of the Furious"

Who doesn't love a good ol' "Fast and the Furious" movie? However, this one will mark the first full movie without Paul Walker, who was included in the last film through CGI.
Universal
May 3: "Logan"

"Logan" will be Hugh Jackman's final performance as the famous "X-Men" character, which many call the best character in the franchise. It is also a coveted role that has defined Jackman's career for 20 years. But "Logan" will offer a new twist on the franchise -- Logan is older, and his powers are fading.

The first "Guardians" film was well-received both critically and commercially, so it's about time Marvel fans are treated to a sequel. And Baby Groot has already cozied up to fans everywhere.

Many are curious to see how a movie adaptation of the classic TV series will turn out -- but with a sexy cast and alums like David Hasselhoff and Pamela Anderson returning, we think it might be worth waiting for.

Come on, Gal Gadot in a movie that exemplifies female empowerment? We're in! The trailers have been epic so far, and DC fans desperately need a pick-me-up after many were disappointed with "Suicide Squad" and "Batman v Superman: Dawn of Justice."
Warner Bros.
July 21: "Dunkirk"

Christopher Nolan's WWII drama has been on people's radar for a while now, and the film will draw in younger fans with its casting of Harry Styles. The movie boasts a great ensemble, comprised of Tom Hardy, Mark Rylance, Cillian Murphy and James D'Arcy.
Warner Bros.
