Nancy Cartwright juggles voices of 'Rugrats' Chuckie, Bart Simpson UPI News Service, 05/27/2021 Nancy Cartwright, who is back as the voice of Chuckie in the Paramount+ Rugrats revival, said the show's change from two-dimensional hand-drawn animation to 3D computer animation makes the characters look more tactile. ADVERTISEMENT "Chuckie's hair looks like it's felt," Cartwright told UPI in a recent Zoom interview. She said the episodes are updated for 2021, with the parents using smartphones and the rugrats playing with tablets. However, Cartwright said technology hasn't changed Chuckie or his friends' approach to childlike adventures. "They've kept the integrity of the writing intact," Cartwright said.
