If you haven't gotten 'round to playing Batman: Arkham City yet (because you hate fun, or aren't yet sold on this whole "bat man" character), your opportunity to rectify such a grave gaming sin is almost at hand. Batman: Arkham City Game of the Year Edition is coming. With it comes every single bit of DLC released for Batman: Arkham City thus far.
And to make sure you are appropriately pumped, Rocksteady has released this behind-the-scenes video that shows Kevin Conroy (Batman), Luke Skywalker Mark Hamill (the Joker), and Stana Katic (Talia al Ghul) getting into character as they do their respective voices.
