Angelina Jolie's two eldest sons, Maddox and Pax, have landed jobs on the set of their mother's new movie.

Directed and co-written by Angelina, First They Killed My Father is adapted from Loung Ung's memoir about the Khmer Rouge genocide in Cambodia during the 1970s.

The actress has now revealed her eldest son Maddox, 14, who she adopted from Cambodia, is helping with research on the film, and Pax, 11, is working with the photography department.

"Pax is doing a lot of the stills (photography)," Jolie told People magazine.

"The whole movie is from a child's point of view."

Maddox previously worked as a production assistant on his mother's film, By The Sea, which also featured his adopted dad Brad Pitt.

The actress revealed Maddox had to be kept away from the film's set whenever his parents were filming uncomfortable scenes.

"Every time we had a fight scene or sexual scene he obviously wouldn't be near us. So he had to work in the parking lot," she said.

Jolie and Pitt have four other children together - Zahara, Shiloh, and twins Knox and Vivienne.
