BRAD PITT and Jennifer Aniston have been living separate lives. Now they’re finally moving on to separate (production) houses.

After their split three years ago, the ex-golden couple continued to collaborate on projects in development at their Plan B production company. While Pitt is sticking with the former joint, teaming with Paramount to shepherd an Amazon-set adventure flick, Aniston and her new producing partner, Kristin Hahn, have inked a deal with Universal Pictures to develop projects for “The Break-Up” star’s Echo Films banner.

According to Variety, Pitt’s crew has acquired the film rights to “Lost City of Z,” an unpublished nonfiction book by author David Grann chronicling British explorer Percy Harrison Fawcett’s ill-fated quest to find the legendary city of Z in the Amazon rain forest.

Pitt is also considering playing the Grann character in the film.

As for Aniston, her Echo Films has several potential starring vehicles in the pipeline.

Aniston is currently finishing up work on the dogcentric comedy “Marley & Me,” co-starring Owen Wilson.
