Angelina Jolie Pitt, isn't worried about getting older. In fact, she embraces it.

Directed and written by Jolie Pitt, the movie was their first onscreen in 10 years, and she says working together strengthened their relationship.

"As much as we can argue and fight, and we all have our challenges, at the end I say, 'My job is to love him.'" Jolie Pitt and Pitt, 51, got married in August 2014 after being together for nine years. They have six children: Maddox, 14, Pax, 11, Zahara, 9, and twins Knox and Vivienne, 7.
