When it comes to the voice of infamous Batman villain The Joker in animated series, video games, and even things like toys and other merchandise, there is simply no one better than Mark Hamill.

The man best known for playing Luke Skywalker in the original (and only, to some) Star Wars trilogy has also handled the voice of the colorful Joker on the Batman and Superman animated series, The New Batman Adventures, more comical shows like Robot Chicken, and of course, in the highly-popular 2008 video game, Batman: Arkham Asylum.

With that game going on to make an insane $562 million, a sequel was guaranteed and pretty much went directly into production on Batman: Arkham Asylum 2, already delivering a teaser trailer this past December (Read: Video Game Awards “˜09: “˜Batman: Arkham Asylum 2″² Trailer). But according to reports, Mr. Hamill himself was not so guaranteed.
