A movie I recommend is "Into The White" which is similar to a REALLY good movie called Joyeux Noel (Merry Christmas). Both are movies about soliders and how they interact with one another during war when they are in a situation where they are unable to fight (or fighting has stopped). And how they connect as humans when fighting is not an option. It's not quite as good as Joyeux Noel, but I still liked it. The most famous person in Into The White is Rupert Grint from Harry Potter fame and he does a great job in his role.
