Sure, Angelina Jolie and Elle Fanning get most of the attention in the "Maleficent" trailer released Wednesday. But the next generation of the Jolie-Brad Pitt acting dynasty gets her chance to shine, too.Twenty seconds into the trailer, a little blonde girl is seen running through a field, and Fanning's voiceover makes it clear that the girl is a young version of Sleeping Beauty/Princess Aurora/Briar Rose. That's Vivienne Jolie-Pitt, the now 5-year-old daughter of Jolie and partner Brad Pitt (and twin to brother Knox).Jolie confessed to the Disney fan gathering D23 that there was an ulterior motive in casting her own daughter. In her spooky costume as the villainess, she scared young children who visited the movie's set, and only Vivienne wasn't frightened."She was the only 4-year-old who wouldn't scream," Jolie said, according to Entertainment Weekly.Us Weekly has reported that two of Jolie's other children, Pax and Zahara, also have small roles in the film.
