Angelina Jolie has persuaded studio bosses to let two more of her children appear in her latest movie Maleficent, after her youngest daughter Vivienne snagged a role.

The actress' four-year-old daughter Vivienne, whose dad is Brad Pitt, was cast as the child version of Elle Fanning's character Princess Aurora in the upcoming adaptation of classic tale Sleeping Beauty.

Now it has emerged Vivienne's older siblings Pax, eight, and Zahara, seven, also have non-speaking parts in the fantasy film, which stars their Oscar-winning mum as the princess' arch enemy.

According to Us Weekly, Jolie's six-year-old daughter Shiloh was also offered to join in the fun, but she lost interest when it came time to step in front of the cameras.

A source tells the publication, "They have smaller parts. Shiloh was supposed to be in it, too, but she was bored and not in the mood during the day her part was supposed to happen, so she ended up not being in the film."
