Christine Cavanaugh (born August 16, 1963, died December 22, 2014) provided the voice of Chuckie Finster from 1991 to 2002.
She was known for other roles such as Gosalyn from Darkwing Duck, Dexter from Dexter's Laboratory, Bunny Rabbot from Sonic the Hedgehog, and Oblina from Aaahh!!! Real Monsters. She was also famed for voicing Babe in the movie of the same name. She was offered to reprise the role in the sequel, Babe: Pig in the City, but declined on the role, which was instead given to Tommy's voice actor, E.G. Daily.
In 2001, Cavanaugh finally retired from voice acting for personal reasons. Nancy Cartwright, best known for voicing Bart Simpson, took over as Chuckie's primary voice actress from the episode "Quiet, Please!" onward, though Candi Milo would fill the role in two video games.
