THEIRS IS THE GLORY is a straight wartime epic depicting the cruelty and horror of the infamous Battle of Arnhem, in which a cut-off airborne division of British soldiers had to hold out against overwhelming odds. A BRIDGE TOO FAR is the better-known version of the story, but this has much to recommend it too: it was made just after the war finished, while the events depicted were still fresh in the memory, and it features many real-life soldiers who were there in the battle. It comes across as more a re-enactment than a film, with some slightly stilted acting in places, but it generally gets the job done and for gritty realism I can think of few comparable movies from the 1940s.
