Over the past quarter-century, veteran voice actor Kevin Conroy has played Batman, both as a solo act and as part of a team, a staggering 258 times, so he knows a thing or two about the Caped Crusader. That includes how to portray the brooding loner amid the ranks of the Justice League.
Talking with IGN, the 60-year-old actor addressed the challenge of sharing the stage with seven other superheroes, offering words of advice that Ben Affleck may want to consider.
"In 'Justice League,' there are often episodes where I'll have four or five lines, where in 'Batman: The Animated Series' I was used to having the entire script to create a portrait of the character," he said. "When you only have a few lines it's much more difficult.
"The temptation is to over-act because you feel such an obligation to completely flesh out the character in just the two or three lines you have," Conroy continued, "and you have to resist that temptation and trust the fact that you know the character so well. That if you just inhabit him, and speak truthfully, it will resonate with the audience. But it is harder to do because the temptation is push it when you're sharing the stage with lots of other actors."
Conroy made his debut as the Dark Knight in 1992 in "Batman: The Animated Series." Since then, he's played the characters in animated series and movies ranging from "Batman: Mask of the Phantasm" to "Justice League" to "Batman: The Killing Joke," and in video games like "Batman: Vengeance," the "Arkham" series and "Injustice: Gods Among Us."
