Brad Pitt and Angelina Jolie are taking their relationship on a new level by becoming business partners as well.

Somewhere between spending time with their four kids and working, moving from city to city, Pitt, 43, and Jolie, 32, squeezed in their schedule yet another project. The two geared up to produce a dramatic series for HBO.

As reported by The Hollywood Reporter, the yet untitled drama, to be written by Scott Burns, who co-wrote “The Bourne Ultimatum” and produced Al Gore's Oscar-winning documentary “An Inconvenient Truth,” will go the behind-the scenes politics of an international aid organization, focusing on humanitarian workers who risk their lives to help others.

Pitt and Jolie together with Burns will become executive producers of the series, which Jolie has longtime fancied, since she worked on the 2003 feature “Beyond Borders,” a drama about disaster-relief workers in war-torn countries.

Both actors have collaborated with HBO in the past, Jolie having played her breakthrough starring role in the cable network’s biopic “Gia,” for which she was honored with a Golden Globe, while Pitt together with Edward Norton, the two having starred together on “Fight Club,” are executive producing the HBO/National Geographic miniseries "Undaunted Courage," now in development.

Most recently, the couple, who moved from New York to Los Angels where Jolie is shooting Clint Eastwood’s new drama, was harshly criticized for constantly changing their residence, fact that might have serious repercussions on their children, adopted Cambodian son Maddox, six, three-year-old Vietnamese son Pax, two-year-old Ethiopian daughter Zahara and 16-month-old biological daughter Shiloh.

As devoted parents, Pitt and Jolie are aiming to give their children a “broad vision of the world,” which is why they’ve been traveling so much.

Over the last 16 months, the family have lived in New Orleans, Paris, Namibia, Prague, India, New York and now Los Angeles.
