8. Battle of Verdun
WWI doesn't get all that many movies made about it, at least not in the last few decades despite being the second largest war in human history. One part of WWI that could become a movie is the Battle of Verdun, a ten month long battle that ended in at least 700,000 casualties, making it one of the most devastating battles of all time. The battle started in February 1916 as the German military sought to break through the French line of defense. The battle consisted of weeks and months long series of attacks and counterattacks by French and German militaries before ending in a French tactical victory. Despite the French technically winning, the losses on both sides ensured nobody really "won" the battle. Besides being the longest and one of the most devastating battles of the war, Verdun might have been the worst imaginable place to live in for a soldier. Both sides were under constant artillery bombardment, trenches became more muddy wasteland than a place to live, and dead bodies became a regular part of the environment. Many soldiers who survived the battle called it the closest to hell anyone could possibly be. Obviously a movie about Verdun would be hard to sit through but it would provide ample opportunity for any filmmaker daring enough to tackle it.
