Brian Austin Green and Gabrielle Union

The CW's Body Politic is shaping up very nicely, with the addition of Brian Austin Green, Gabrielle Union and others to the Washington, D.C.-centric pilot's growing ensemble.

Should Body Politic get ordered to series and Fox's Terminator is unplugged, Green will play the "boy wonder" adviser to the president of the United States, says the Hollywood Reporter.

Union, in turn, will bring it on as BAG's girlfriend, a legislative director.

Also feeling the CW's Body are Jay Hernandez (Six Degrees), playing a naval officer, and Reaper's Jenny Wade, as an idealistic D.C. up-and-comer.

Body Politic's previous castings include Minka Kelly, Jason Dohring and Tim Matheson.
