Cruella will take a 1970s punk-rock approach, according to Stone.
Sean Bailey, Disney’s president of production, said the film will ask where de Vil’s dislike of animals comes from.
Speaking at D23, Disney’s biennial convention, he said: “How did she get that way, and how did she get so cruel?”
Stone could not appear in person at the convention, instead sending fans a video message from London. Dame Emma Thompson will also appear in Cruella, which is due to be released in May 2021.
Stone is not the first actress to portray de Vil in a movie. Glenn Close famously pulled on the black and white wig for 1996’s 101 Dalmatians.
