A first look at 1917, the upcoming new war film from Sam Mendes, has landed.

Set at the height of the First World War, it will tell the story of two young British soldiers who are given a seemingly impossible mission – they must cross enemy territory and deliver a message that will prevent a deadly attack on hundreds of soldiers.

The large cast boasts such names as Richard Madden, Benedict Cumberbatch, Mark Strong, Colin Firth and Andrew Scott.

1917 is set for an Australian cinema release on January 9, 2020.
