so theres been lots of Batman animated series and so lots of voice actors have portrayed the many different characters.

who do you guys think have played these characters the best?

this site has a comparision of the actors and characters and sound clips so you can judge for yourself who's the best

for me
- Batman - Kevin Conroy
- Joker - Mark Hamill
- Robin - Loren Lester

lol, looks like i picked all the voice actors from the 90s series :P

Mark Hamill is probably the best acquisition of them all. He's so surprisingly excellent at voicing Joker that they used him for the new Arkham Asylum game (the next game I'm definitely getting). I wonder if he'll be considered for Heath's succesor in the movies. Unlikely, I know, but it wouldn't be the first time Nolan surprised us.
