For many people, the best Batman wasn't an actor in any of the live-action movies. It was Kevin Conroy, who first voiced the Caped Crusader in "Batman: The Animated Series" in the 1990s. Since then, Conroy has played Bruce Wayne and his nocturnal alter ego in numerous cartoons, animated features and the "Arkham" series of video games. On a panel this past weekend at Stan Lee's Los Angeles Comic Con, hosted by Londyn Jackson of the History of the Batman podcast (transcription via Screen Geek), he weighed in on his favorite portrayal of the Dark Knight.
"Each actor brings such a different art to the character, it’s really fun. I think Christian Bale’s Bruce Wayne was probably the best Bruce Wayne," Conroy said. As for Bale's take on Batman, Conroy was a bit more critical of Bale's death-metal inspired take, saying "I think the voice he used for Batman was bizarre."
Conroy even gave his two cents on the most recent actor to wear the cowl saying, "[As for] Ben Affleck, a lot of people gave him a lot of crap for getting cast. People on Twitter were going crazy about it and I said, “Wait a minute, wait a minute. Give him a chance.” I think he surprised a lot of people. He’s really wonderful. He does really well on both Batman and Bruce Wayne."
In "Batman: The Animated Series", Conroy revolutionized the way actors protray Batman (and by extension, superheroes in general). He developed two different voices, one for Bruce Wayne and one for Batman. So when offers feedback to an actor on both roles, he's coming from a place of expertise. When you get down to it, no one has been the Bat for longer than Kevin Conroy.
