Angelina Jolie drafts kids into new film

Angelina Jolie has brought in more of her own children for roles in her new film 'Maleficent'.

Pax and Zahara Jolie-Pitt will join their sister Vivienne Jolie-Pitt in the film, making four members of the Jolie-Pitt family in the cast in total.

But the addition may have been at the cost of their other sister Shiloh, who was originally cast in the film but was dropped, according to Us Weekly, because 'she was bored and not in the mood during the day her part was supposed to happen'.

They are the first film roles for Pax, aged 8, and Zahara, aged 7, while sister Shiloh did make it onto screen as a baby in 'The Curious Case of Benjamin Button', which starred her father Brad Pitt.

The roles will be non-speaking, according to reports, while Vivienne has snagged a speaking part as the toddler version of Princess Aurora, played by Elle Fanning.

The film began shooting in London this summer, with Jolie playing the evil queen Maleficent from Walt Disney's 'Sleeping Beauty'.

It also stars Sharlto Copley, Juno Temple, Sam Riley, Miranda Richardson, Imelda Staunton and Lesley Manville.

It's due for release in March, 2014.
