Paths Of Glory. 1957.
When a group of soldiers refuse to attack the enemy, they are summoned for a court martial, being accused cowardice, their commanding officer stands to defend them.
Kubrick displays great cinematography in the small but effective small battle sequence, even in the trenches Kirk Douglas slowly walking by his men shows great control when the bombs are going off and doesn't even flinch a muscle. There is a slow opening for about 5-10 minutes long but that does pay off well, this focuses on the French against the Germans in 1916 and shows how ignorant some commanding officers can be with their denial of being shell shocked and fear of loosing the battle.
