As we've talked about here in the past, when Diedrich Bader was hired to voice the Batman on Batman: The Brave & the Bold, his rendering of the Caped Crusader was almost a perfect mimic of Kevin Conroy's definitive portrayal of the World's Greatest Detective. Seems as though Bader had had some practice.
In 1993, Bader was a relative unknown when he was cast in The Searcher, 1/2 of Fox's short-lived Danger Theatre anthology series, which lasted 2 months. Listen very carefully to Bader as the Searcher.
Robert Vaughn (ex-The Man From U. N. C. L. E, The A-Team) was the narrator. We'll have more on Danger Theatre over at The Land of Whatever another time.
