She said, "Maddox worked hard. It's up to him. This [film] is very important to him, but I think so."
The 'Maleficent' star also shared that Maddox, as well as Pax, Zahara Jolie-Pitt, 12, Shiloh Jolie-Pitt, 11, Knox Jolie-Pitt, 9, and Vivienne Jolie-Pitt, 9, might want to collaborate on something creative together in the future.
"I might dream. If I am to continue to be in this business I'd love to work with my children if they choose to be in this business," noted Jolie.
But, she wants her children to pursue passions by their own volition, and the same goes for their interest in social advocacy.
She explained, "My daughter [Shiloh] has gone to refugee camps. Whenever I go on humanitarian trips, they want to go with me. I never force them. I want them to respect people of diversity."
