Lou Diamond Phillips, Ming-Na, Elyse Levesque and Alaina Huffman are the latest actors to join Sci Fi's relatively star-studded new series "SGU: Stargate Universe."

Sci Fi announced Wednesday (Feb. 25) that "SGU: Stargate Universe" has already begun production in Vancouver (where else?) and will premiere in October on the cable network. 

MGM is producing the new series, which is described as "edgier and younger in tone" and will premiere with a two-part episode directed by Andy Mikita.

"SGU: Stargate Universe" focuses on a group of soldiers, scientists and civilians who are forces through a Stargate and find themselves stuck on an abandoned, ancient space vessel locked on an unknown course. 

Phillips, Ming-Na, Levesque and Huffman join previously announced castmembers Robert Carlyle, Justin Louis, David Blue, Jamil Walker Smith and Brian J. Smith.

According to Sci Fi, Phillips ("La Bamba") will play Colonel Telford, a life-long military man and the leader of the original expedition.

Ming-Na ("ER," "Inconceivable") will play a human resources executive within the international oversight committee that governs the Stargate program. We have absolutely no idea what that means, but apparently it gives her a false sense of superiority.

Huffman ("Smallville") will play an Air Force medic forced to rise to a steep challenge with very little experience.

Levesque's ("Men in Trees") character is described as the daughter of a U.S. Senator, who has political ambitions herself, but also a wild side.
