On playing the Riddler in "Batman" (1966): "When I was first approached to play the Riddler, I thought it was a joke. Then I discovered the show had a good script and agreed to do the role.... Now I am in love with the character. I developed the Riddler`s fiendish laugh at Hollywood parties. I listened to myself laugh and discovered that that the funniest jokes brought out the high-pitched giggle I use on the show. With further study I came to realize that it wasn`t so much how I laughed as what I laughed at that created the sense of menace."
I do not do hundreds of impressions. My entire repertoire of impressions numbers less than 50. I never set out to do an impression of a person. However, when something a star does suddenly sparks my imagination, I find myself doing an impression of him -- first for my amusement, later for my repertoire.
(on working with Lynda Carter on "Wonder Woman" (1976)) I met Lynda years before she did Wonder Woman, in Chicago. I forget the name of the club. At that time, she was working as a singer. She was a good-looking lady and sang well. And I never saw her after that until I did that Wonder Woman episode. She remembered me. I played the Toymaker, but I can`t remember anything else of any significance that happened during the shooting.
