Angelina Jolie and Vivienne Jolie-Pitt in Maleficent
Set for release in May, Angelina plays one of the scariest Disney villains ever, and revealed that Vivienne got the part of Princess Aurora because she was the only child that didn't cry seeing Angelina's frightening costume. "We think it’s fun for our kids to have cameos and join us on set, but not to be actors. That's not our goal, for Brad and I, at all. But the other three- and four-year-old [performers] wouldn’t come near me. It had to be a child that liked me and wasn't afraid of my horns and my eyes and my claws. So it had to be Viv."
