Looks like Batman: Arkham City is the last time we'll hear Mark Hamill voice the Joker.

Hamill indicated on Twitter he's done voicing the Clown Prince of Crime.

"Hello/Goodbye Joker! I've enjoyed every minute behind the wheel of the Crown Prince's crazy car- I'm going to miss him more than I can say!!"

This news should come as no surprise as Hamill said in an interview with IGN back in May that Batman: Arkham City would be his final project.

Hamill began voicing Joker back in 1992 in Batman: The Animated Series and would continue to do so in episodes of Superman: The Animated Series, The New Batman Adventures, Justice League, and Static Shock. He also played the Joker in two animated films: Batman: Mask of the Phantasm and Batman Beyond: Return of the Joker.
