Fan CastingBatman: Arkham Origins

Description of Joker:

During a particularly snowy winter, near Christmas, a man whom no one had ever seen or heard of emerged in Gotham with plans of destruction and chaos for the city simply for the sake of it. A man known simply as The Joker, a villain who was driven by a lust to create social disorder and desired nothing but anarchy to feed his sadistic appetites and morbid, dark sense of humor. With a particular hatred for the Dark Knight himself, having blamed the hero for making him who he was, and a hunger for revenge against him, the Joker began to make his schemes to destroy Gotham and make Batman suffer in the process.
