Lou Diamond Phillips in 'Stargate Universe'

Ming-Na also among Sci Fi series' new cast members

Lou Diamond Phillips, Ming-Na, Elyse Levesque and Alaina Huffman round out the cast of Sci Fi Channel's new original series "SGU: Stargate Universe."

The four join previously cast Robert Carlyle, Justin Louis, David Blue, Jamil Walker Smith and Brian J. Smith on the MGM TV-produced series, which began production last week in Vancouver.

Edgier than its franchise predecessors, "SGU" follows a band of soldiers, scientists and civilians who must fend for themselves after they are forced through a Stargate when their hidden base is attacked. The survivors, led by Dr. Nicholas Rush (Carlyle), emerge aboard an ancient ship, which is locked on an unknown course and unable to return to Earth.

Phillips, repped by Global Artists and manager JB Roberts, will play Col. Telford, a lifelong military man and the chosen leader of the ill-fated expedition.

ICM-repped Ming-Na will play Camile Wray, a human resources executive with the international oversight committee that governs the Stargate program.

Levesque ("Smallville") will play Chloe Armstrong, the daughter and aide of a U.S. senator. She is repped by Kirk Talent Agencies. Huffman ("Smallville") will play MSgt. Tamara Johansen, a field medic assigned to treat the seriously wounded. She is repped by the Paul Kohner Agency and New Wave.

"SGU" is slated to launch in October with a two-part opening episode directed by Andy Mikita.
