Fan Casting The Mugger in Darren Aronofsky's Batman: Year One

No name. No face. No credits. A shadow with a gun who struggles with Thomas Wayne, grabs Martha by the throat, and fires four shots. He is not a character but a force of nature—random, senseless violence. His face is never clearly seen because he could be anyone. He is the reason Batman exists. He is never caught, never named, never remembered.
