Knox Jolie-Pitt's 4-year-old twin sister will play the child version of Elle Fanning's Princess Aurora in the live-action movie, a reimagining of the fairy tale Sleeping Beauty, told from the villainess' perspective.
"It's a really great script, and I'm having a lot of fun. I've already got my horns fitted," Jolie told Entertainment Weekly of her titular role in March. "My kids are very happy."
Jolie's twins were spotted visiting her on set in Buckginhamshire, England, in late June. She and fiance Brad Pitt, 48, are also parents to Maddox, 11, Pax, 8, Zahara, 7, and Shiloh, 6.
Like Jolie, Vivienne is breaking into showbiz at an early age. Jolie appeared onscreen for the first time at age 6 in the 1982 film Lookin' to Get Out. Her father, Jon Voight, 73, starred and co-wrote the movie. But Vivienne isn't the first Jolie-Pitt child to appear on the silver screen: A young Shiloh had a brief role in Pitt's 2008 film The Curious Case of Benjamin Button.
