She'll voice both 15-year-old Duncan and his highly stressed, always-knows-best mom, Annie.
Fox greenlit 13 episodes of the series, which is written by "The Simpsons" veteran Mike Scully and his wife, former "Simpsons" writer-producer Julie Scully.
"'Duncanville' is one of the freshest animated concepts we've seen, and has an insane pedigree of comedic talent across the board," said Michael Thorn, President, Entertainment, Fox Broadcasting Company. "We've enjoyed a long, incredible run with Mike and Julie, and everything Amy does is pure genius. Having the voice talents of Rashida and Wiz join her makes this show the complete package. I can’t wait to have them all together when we add 'Duncanville' to our growing animated slate."
Look for it during the 2019-2020 season.
