Looks like they’re dropping Luanne rather than bringing in a new voice actor. She was voiced by Brittany Murphey.

“We are all so excited to welcome back Hank, Peggy and Bobby, and to see what they have to say about the world we live in and continue the conversations we began years ago,” said Craig Erwich, president, ABC Entertainment, Hulu and Disney Branded Television streaming originals. “This show has all of the perfect ingredients to meet this moment in animation at Hulu, and we’re so thankful to be having those conversations alongside this talented group.”
