Brown Johnson, president of animation for Nickelodeon, announced today at TCA that the new animated comedy series Teenage Mutant Ninja Turtles will premiere on September 29. Turtle voices on the panel included Sean Astin (Raphael), Jason Biggs (Leonardo) Greg Cipes (Michelangelo) Rob Paulsen (Donatello) and Mae Whitman (April). The session started off on a humorous note. Johnson noted that the TCA crowd is very different from the folks that the show’s creative team met at Comic-Con: “At Comic-Con, we had 3,000 people, and they were all dressed as turtles”, she said.
