OOhh...damn it. I was only thinknig of Live Action and not Voice actors. The BTAS reference gave the answer. Efrem Zimbalist, Jr.; mentioned in Secret Origins of the World's Greatest Super-Heroes in the first story "Batman: The Man Who Falls"; for his role in The F.B.I Series. Actually, it was me who added that piece of trivia in the issue's page.
