Sam Mendes, the director of Skyfall and Spectre, is taking us back over 100 years this Christmas to World War I in 1917. Starring George MacKay and Dean-Charles Chapman as a pair of young British soldiers, they are tasked with crossing enemy territory to deliver a vital message to call off an attack that would kill thousands of British troops but they only have limited time to get the message to the proper channels. Colin Firth, Richard Madden, Benedict Cumberbatch, Mark Strong, and Andrew Scott co-star and it will be out on Christmas Day in December. It looks amazingly shot and epic in scope and you can check out the trailer below.
