Angelina Jolie revealed some of her kids have a small role in her new movie Kung Fu Panda 3, although she did admit she had to push them into it.

Jolie said she took four of her six kids with husband Brad Pitt to work with her on set; Pax,12, Zahara,10, Shiloh, 9, and Knox, 7, and they provided the voices for the pandas making noises in one scene.

"They were kind of shy," Jolie 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."

Jolie, who adopted three of her children, also praised the film’s writers for embracing the theme of children having two fathers - biological and adopted.

"It handled it well, because it didn't brush over it," she said of the film."It shows that it's complicated and it's not easy and it's not over in a happy second."

The cast also includes Kate Hudson, Dustin Hoffman and Jackie Chan.
