Something that draws fans to director Quentin Tarantino is his film's violence and how it can be stylized, but still so brutish that it can be hard to watch. It seems like another director has found that mix in a war movie that challenges Tarantino's own World War II picture.

Find Out Why Brad Pitt Might Be More Similar to His New "Fury" Role Than We Think

Fury, which came out on Friday, can have brutality that feels to real, as The Daily Beast reviewer Nico Hines noted on Monday, and he said it is akin to Tarantino's own Inglorious Basterds. But the lack of subtlety is something director David Ayer was trying to capture.

"The conflict itself truly was this sort of battle between good and evil," said Ayrer, speaking after a screening at the London Film Festival.

"People often project the moral clarity of the conflict itself into the daily lives of the soldiers, but that wasn't the case. For the troops on the ground or in the tank turrets it was incredibly morally murky just like any conflict."

It is a film that doesn't hold back any punches and even it's star, Brad Pitt, knows that it is capturing a lot of the darkness in war rather than the moments that seem to glimmer with hope.

"This is not a film about sides and who's winning, what this is, for me, was a film about that cumulative psychic trauma, that dent in the psyche that every soldier carries to some extent and endures and is then meant to go home with," said Pitt in London.

"War is hell. Talking to the vets and even the vets that are recently home, one guy said 'Listen, war is ludicrous. If you look at it, it is ludicrous, so you don't.' It is an amazing fact of human nature that one year you'll be chopping each other up, the next year you'll be sharing a pint."

It seems like Ayer has crafted a film steeped in violence and blood, but one that also knows that the heart of the character is still there to show that war is both outward and inward.
