Brad & Angelina Teaming Up for HBO Series

Brad Pitt and Angelina Jolie are already partners on a handful of huge projects - namely Maddox, Shiloh, Zahara and Pax - but now the pair are going into business together.

Pitt, 43, and Jolie, 32, are teaming up for their first producing project, a new series for HBO, according to the Hollywood Reporter.

And it's a subject close to their hearts: The untitled drama will go behind the scenes of an international aid organization and follow workers who put their lives in danger to help others. The series is being written by Scott Burns, who co-wrote The Bourne Ultimatum and produced Al Gore's Oscar-winning documentary An Inconvenient Truth.

After spending some family time in New York (where Pitt also filmed his new movie Burn After Reading), the couple recently returned to Los Angeles, where Jolie is filming The Changeling with Clint Eastwood.
