According to Pitt, the training for “Fury,” which included lots of conversations with actual veterans, becoming familiar with the tank, and even getting into fights with his co-stars. The relationship between the soldiers in “Fury” is completely antagonistic, and while they are careful to work together to complete any kind of offensive mission, they also keep their close friendships low; the movie is too dirty and depressing to allow any kind of warmth between genuine platoons. The first three months of production – a long time for any film – are made up of actual training, combat, and training camp. Pitt described the training program thus:
“[B]oot camp sounds like a gimmick for the actors, but we’ve got some of the best SEALs designs for us. And it’s truly an incredible experience in the way that it’s designed to break us, make us understand the hard, leave us cold, wet, hungry, physically exhausted, and then deliver gives us tasks that bring us together, bring us together, uncover each other’s weaknesses and strengths, and establish a dissecting order. It was truly a profound experience. “
Deep, perhaps, but horrible. The actors can only bond over shared suffering, perhaps authentic to the way soldiers are bound on the battlefield. When pushed to the point of death, with the resolve of a broken person, clinging to each other in the gloom, the need for violence can perhaps feel like close friendship.
And that’s not the end of it. In fact, Ayer, in addition to pushing them to their physical limits, is also careful to hit his actors on the head.
