The project marks the first onscreen roles for Pax, 8, and Zahara, 7, as well as for 4-year-old Vivienne. The three tabloid fixtures, the offspring of Jolie and Brad Pitt, follow in the footsteps of sibling Shiloh Jolie-Pitt, who appeared as a baby in David Fincher's The Curious Case of Benjamin Button alongside her father.

Pax and Zahara's roles in Maleficent will be non-speaking.

THR reported Vivienne's casting in August. She plays the toddler version of Elle Fanning's Princess Aurora. That role is a speaking role.

The Robert Stromberg-helmed film, which is currently shooting, will bow March 14, 2014.
