Rocksteady has commented on the Hamill issue themselves: Mark Hamill, a classic voice of the joker in not only Batman: Arkham City, but countless other Batman series, recently announced his retirement. However, the narrative developer of Rocksteady, Paul Crocker, calls Mark Hamill “a dirty liar” for his recent statements, saying:
There are two things about Mark Hamill you need to know; one is that he’s a dirty liar. In all honestly, I’ve done all the [voiceovers] with him for years, and he’s never, to the best of my knowledge, actually said, ‘I don’t want to do this anymore’. That’s just got blown out of proportion.
Hopefully he will be the voice of the Joker in potential future installments of the Arkham series
