The 13-year-old boy will help out on the set as the production assistant, reported the Daily Mirror.
The 'Maleficent' actress, who is the director of the film, has reportedly given Maddox his first job after he joined her on the set of her movie 'Unbroken' in Australia earlier this year.
Maddox was apparently seen around the set quite a bit, watching the goings-on and also talking to the movie actors as they shot in Sydney.
