Some disappointing news coming from Mark Hamill.

According to his twitter account, his role as Joker in Batman: Arkham City will be his last job voicing the famous bad guy.

Hamill had been voicing Joker for some time on TV and made his jump over to video games in the critically acclaimed Batman: Arkham Asylum.

If there's something worse than losing a hand (Star Wars Joke!) it's losing his great talent voicing the role.
