Vivienne Jolie-Pitt was just 4 years old when she appeared in her first film. She played the younger version of Elle Fanning's Aurora in the 2014 film, "Maleficent," in which her mom played the titular role. In a 2014 interview with Entertainment Weekly, Angelina explained that this adorable casting choice wasn't all about getting Vivienne on the big screen; it also had a bit to do with how scary that Maleficent costume was. Jolie explained: "[The] other 3- and 4-year-old [actors] really wouldn't come near me. ... it had to be a child that really liked me and wasn't afraid of my horns and my eyes and my claws. So it had to be Viv."
In 2016, two years after Vivienne's role in "Maleficent," Knox Jolie-Pitt made his own film debut as a voice actor. He played Ku Ku in "Kung Fu Panda 3" alongside Angelina, who plays Tigress in the franchise. It may come as a surprise that Jolie and Pitt have encouraged their children to appear in movies, considering their desire to keep the kids out of the public eye. Yet, for Brangelina, these casting choices have been more about enjoying a bring-your-kids-to-work day than launching lifelong careers. "We think it's fun for our kids to have cameos and join us on set, but not to be actors," Angelina explained, adding, "That's not our goal, for Brad and I, at all. I think we would both prefer that they didn't become actors."
