We're only 1 day out from the release of the Harley Quinn's Revenge DLC for Batman: Arkham City and the Game of the Year edition of that game, and now we have a little behind-the-scenes video showing the people who've provided the voices for the games...and cartoons...and....others.

Mark Hamill and Kevin Conroy have been providing the voices for The Joker and Batman, respectively, for 20 years now and it's cool to see them in action. Particularly Mark Hamill, since I've always found it hard to imagine that nutty Joker voice coming out of Luke Skywalker. These guys are so familiar with the characters that they've even had chunks of dialogue rewritten for them to match what they think the character would say. Mark Hamill will supposedly not be voicing The Joker anymore, so enjoy it while you can.



Last but not least, there's also the beautiful Stana Katic from Castle voicing Talia al Ghul
