premise: Frank John Gorshin, Jr. (April 5, 1933 – May 17, 2005) was an American character actor, impressionist, and comedian. He was perhaps best known as an impressionist, with many guest appearances on "The Ed Sullivan Show" and "Tonight Starring Steve Allen". His most famous acting role was as the Riddler on the live-action television series "Batman".
hypothesis: Gorshin had an acting role on an animated Batman series.
reason: It says he was on the live action series but doesn't say whether he was also on one of the animated Batman series.
