Did you know that Dunkirk is the first movie by Christopher Nolan based on historical events? 

Christopher Nolan's latest WW2 blockbuster has some interesting stories to tell.

First have a look at the trailer above!

1)For the sea battle sequences, Christopher Nolan decided to use real naval destroyers instead of CGI, continuing his own tradition. At one point, there were as many as 62 ships out on the water during one day of filming. He also placed cardboard cutouts of soldiers and military vehicles in the distant background of certain shots to create the illusion of a large army.

2) 1,500 extras, a crane and a Spitfire plane were used to recreate the miraculous evacuation of 338,000 allied troops.

3)The film is told from three points of view: infantry, navy and air forces. Christopher Nolan said that "for the soldiers who embarked in the conflict, the events took place on different temporalities. On land, some stayed one week stuck on the beach. On the water, the events lasted a maximum day; and if you were flying to Dunkirk, the British spitfires would carry an hour of fuel. To mingle these different versions of history, one had to mix the temporal strata. Hence the complicated structure; even if the story is very simple. Do not repeat it to the studio: it will be my most experimental film.”

4) This is Christopher Nolan's first movie since Insomnia (2002) not to feature Michael Caine as an actor.

5) This is the first Christopher Nolan movie that is based on historical events. All of his other movies have been original scripts, remakes, and adaptations of novels, short stories, or comic books. Dunkirk is also Nolan's first war movie.

6) Christopher Nolan reportedly received a $20 million salary against 20% of the box office gross, the biggest deal for any director since Peter Jackson received the same amount with King Kong (2005).

7) Harry Styles reportedly had a personal bodyguard on set, to fend off overly zealous fans.

8) This will be cinematographer Hoyte Van Hoytema's second collaboration with Christopher Nolan. The previous was Interstellar (2014).

9) Continuing his advocacy for film over digital formats, Christopher Nolan chose to shoot the movie in a combination of 15/70mm IMAX film and Super Panavision 65mm film in order to achieve the maximum possible image quality. Following The Master (2012) and The Hateful Eight (2015), Dunkirk (2017) will be the third major motion picture of the current decade to be primarily shot and shown theatrically in 70mm.

10) For composer Hans Zimmer, this is the sixth collaboration with Christopher Nolan. They previously worked together on The Dark Knight Trilogy, Inception (2010), and Interstellar (2014). Zimmer received a Oscar nominations for both Inception and Interstellar.
