Charlie Adler

Was the original voice of "Buster Bunny" on Tiny Toon Abenteuer (1990). He reportedly quit after learning that he was not going to receive a role on the upcoming series, Animaniacs (1993), despite having been the lead on "Tiny Toons" while other actors form the series, such as Rob Paulsen, Maurice LaMarche and Tress MacNeille, were being given roles on Animaniacs (1993), and was further angry when he learned that a prominent role (Wacko) was given to Jess Harnell, who was a relative newcomer to voice acting at the time while Adler himself had much more experience. Adler was replaced by John Kassir, better known as the voice of the "Crypt Keeper" on Geschichten aus der Gruft (1989).

[on working with Mel Blanc] It was exciting just to be in the same room with him. By that point Mel was using an oxygen bottle, but I think it was just a ruse by his doctor. His choice was to either stop smoking or blow us all up.
