Everyone knows Frank Gorshin as being the Riddler in the 1960's Batman.
However, not too many people remember the other Riddler from the show, played by John Astin.
Towards the end of season two, Frank Gorshin was beginning to get upset at his pay. He believed that he was important to the success of the show and needed his paycheck to reflect that. The network, on the other hand, saw things differently. They didn't think that Mr. Gorshin was as important to the show as he thought. Thus Gorshin was out and John Astin was in.
