Emma Stone wasn’t shocked by how dark Cruella de Vil’s backstory is in Disney’s new live-action “Cruella.”

“Surprise is hard when you’ve been attached to the movie for four years and you’ve seen many different incarnations of the script,” Stone told Variety‘s senior culture and events editor Marc Malkin while she promoted the film with co-star Emma Thompson. “I wasn’t surprised because I had seen all the permutations it was going through.”

Shock value aside, Stone said it was exciting to dive deep into the backstory of the sinister Disney villain.

“I thought that this was a really exciting and interesting reimagining of a character that we feel like we know on a surface level,” Stone said. “It was fun to go deeper into what makes her tick and what makes her so evil.”

Thompson, who plays Cruella’s fashion designer nemesis Baroness, said her favorite Cruella look was the dress that she wears on the back of the garbage truck.

“The thing that I loved about it was that it was real,” Thompson said. “This skirt was actually attached to her, it wasn’t CGI’ed, they drove off fast and they did that amazing fishtail thing for real on camera. I was there to see it, and it was epic.”

While preparing for her role, Thompson said she took some inspiration from Alexis Carrington Colby on “Dynasty.” Portrayed by Joan Collins on the 1980s primetime soap, Alexis is a legendary TV character infamous for being the ultimate backstabbing power-hungry diva.

“My wonderful makeup designer, Naomi Donne, actually drew quite a lot from darling Joan Collins, who couldn’t be nicer but who’s played some real meanies,” Thompson said. “She has wonderful narcissism, and of course, that’s what Baroness has got to the nth degree. She’s dreadful.”
