The upcoming new WWI film from Sam Mendes, 1917, aims to immerse us in the action like never before.

This is far from the first film to make such a claim, however they’re really going all out on this one.

The story revolves around two young British soldiers who are given what amounts to an almost impossible mission – deliver a message, deep in enemy territory, that will stop their men from walking into a deadly trap.

It all takes place outside, and is all put together as essentially one shot, in real time. Check out the featurette below which takes us behind the scenes of this amazing-looking production.

Starring George MacKay, Dean-Charles Chapman, Mark Strong, Andrew Scott, Richard Madden, Claire Duburcq, Colin Firth and Benedict Cumberbatch, 1917 is set to land in Australian cinemas on January 16, 2020.
