Acclaimed filmmaker Christopher Nolan returns for the first time since 2014's sci-fi epic Interstellar to give audiences the true-life WWII drama Dunkirk this summer. After a short teaser earlier in the year, we now have the full-length trailer, which marks the big screen debut of musician Harry Styles. It also reunites Nolan with some of his favorite actors, including Batman vets Tom Hardy and  Cillian Murphy.

Dunkirk marks the event that shaped our world. Dunkirk opens as hundreds of thousands of British and Allied troops are surrounded by enemy forces. Trapped on the beach with their backs to the sea they face an impossible situation as the enemy closes in. Today, we get to see more of the action and thrills of this harrowing moment from history with all-new footage. And it surely impresses.

Christopher Nolan went after a mostly unknown cast for his army of young soldiers faced with the unthinkable. The filmmaker is directing from his own original screenplay, working with an ensemble that includes Fionn Whitehead (ITV's Him), Jack Lowden ('71), and Aneurin Barnard (Citadel). Recent Academy Award winner Mark Rylance (Bridge of Spies), Kenneth Branagh (Valkyrie), and James D'Arcy (Cloud Atlas) are the more experienced members of this large cast.

Dunkirk is a large scale film, shot using a combination of IMAX 65mm and 65mm large format film photography for maximum image quality and high impact immersion. Christopher Nolan and his team traveled to many of the real locations depicted in the movie, where these terrifying events took place, offering a sturdy foundation for the background of this story. Nolan is producing Dunkirk alongside longtime producing partner Emma Thomas.

The behind-the-scenes creative team includes director of photography Hoyte van Hoytema (Interstellar, Spectre, The Fighter), production designer Nathan Crowley (Interstellar, The Dark Knight Trilogy), editor Lee Smith (The Dark Knight Trilogy, Elysium), costume designer Jeffrey Kurland (Inception, Bullets Over Broadway), and visual effects supervisor Andrew Jackson (Mad Max: Fury Road).

One of the more bold ideas seen in the movie is the crashing of a real-life WWII plane. Director Christopher Nolan will be using a vintage World War II plane for this moment. While unconfirmed, a report from earlier in the year claimed that Warner Bros. paid a massive $5 million sum to purchase this vintage plane, only to demolish it as part of the production. The plane was reportedly outfitted with several IMAX cameras to film scenes inside before the big crashed.

Warner Bros. Pictures is distributing Dunkirk worldwide and has slated the film for a July 21, 2017 release, putting it up against EuropaCorp's Valerian and the City of a Thousand Planets and Universal's Girl Trip. It will arrive in theaters one week after War For the Planet of the Apes makes its big debut ion July 14 alongside the sure to be hit comedy Bad Dads. It will be followed a week later by Stephen King's Dark Tower adaptation and the drama The Coldest City.

Take a look at Dunkirk and all the action it has to offer courtesy of Warner Bros. We also have the first Dunkirk poster, which arrived earlier in the week. This will not be your average summer popcorn tentpole thriller. It brings the weight of a changing world, and the adventure of a lifetime for a group of soldiers, some of whom weren't lucky enough to make it home.
