Could we soon be seeing another generation of Jolie-Pitts on the big screen? Angelina Jolie has revealed that four of her children will feature in the animated film Kung Fu Panda 3 after she took them to work with her one day.The mum-of-six said that while her children Pax, Zahara, Shiloh and Knox don't share their parents' passion for acting, they did get a taste of what it was like to be a movie star by providing animal noises for some of the pandas in the film."They were kind of shy," Angelina told ET. "They don't really want to be actors, but I didn't want them to miss the opportunity. They came in, and they had a lot of fun with it."It is not the first time Angelina and Brad Pitt's children have made on-screen appearances; their youngest daughter Vivienne played a young Aurora in Maleficent, while Zahara and Pax had small walk-on roles.Their eldest son Maddox Jolie-Pitt has also been helping his mother with her work behind the camera, as he has been recruited to assist with production on her upcoming adaptation of First They Killed My Father: A Daughter of Cambodia Remembers – the memoir of Cambodian human rights activist Loung Ung about surviving the Khmer Rouge regime.Angelina has also worked with her husband Brad on two occasions, most recently in By the Sea, which the actress also directed. While some friends advised them not to work together again following their wedding, Brad has since admitted he doesn't mind his wife calling the shots."It's surprising how much I enjoy the direction of my wife," Brad told V magazine. "She's decisive, incredibly intuitive, and might I say sexy at her post. I trust her with my life."
