Animaniacs [SEP] Creation and inspiration
The "Animaniacs" cast of characters had a variety of inspiration, from celebrities to writers' family members to other writers. Executive producer Steven Spielberg said that the irreverence in "Looney Tunes" cartoons inspired the "Animaniacs" cast. Tom Ruegger created "Pinky and the Brain", a series Sherri Stoner had also written for, after being inspired by the personalities of two of his "Tiny Toon Adventures" colleagues, Eddie Fitzgerald and Tom Minton. Ruegger thought of the premise for "Pinky and the Brain" when wondering what would happen if Minton and Fitzgerald tried to take over the world. Deanna Oliver contributed "The Goodfeathers" scripts and the character "Chicken Boo", while Nicholas Hollander based "Katie Kaboom" on his teenage daughter.
