The video above reveals star Robert Pattison as the Caped Crusader and shows a dark, gritty, and violent new take on the iconic superhero. The footage plays against a haunting version of Nirvana's "Something in the Way."

"It's about the early days of him being Batman and he's very far from being perfect," Reeves told fans during the FanDome event. "One of the things that are interesting is learning how to be Batman. It's a criminological experiment. He's trying to figure out what he can do to change this place. He's seeing he's not having any of the effect he wants to have. That's when the murders start to happen ... and it opens up a whole new world of corruption. Without being an origin tale, it ends up touching on his origins. It's a detective story, a mystery, it's got, of course, action, and it's incredibly personal for him. He's kind of a growing legend and [criminals] are afraid of him. He's not a symbol of hope yet. One of the things he has to deal with is how he's perceived ... What was exciting for me was not doing the origin [story] but to meet him in the middle and to see him make mistakes and grow and fail and be heroic in a way that felt very human and very flawed."
