It's official: Christopher Nolan's next venture will be a World War II film. Yesterday we reported on rumors of Nolan's super secretive trips to Dunkirk, France with his brother Jonathan Nolan, the location of French evacuation during WWII. Now Variety confirms that Dunkirk will be Nolan's next film with an original screenplay from the director.

The film will center on Operation Dynamo, a mission to evacuate the British Expeditionary Forces and allied soldiers surrounded by German troops in Dunkirk in the summer of 1940. Warner Bros has yet to release further details about the film, but so far Tom Hardy, Kenneth Branagh and Mark Rylance are in talks to join the large ensemble. (Mmm, smell those Oscars?) Nolan plans to cast unknown leads and has already been testing teenagers in London.

We also know Nolan is sticking to film for this war epic. Just as Quentin Tarantino recently hinted atDunkirk will be shot on a combination of IMAX 65mm and 65mm large format film. Here's to hoping we get to see the final film projected in its original format. There's hope now that Tarantino has retrofitted theaters for The Hateful Eight, but then again, in just a few short days of its release there have already been issues with some theaters. Why don't these guys just start their own theater chain together?
