Justin Louis, David Blue, Brian J. Smith and Jamil Walker Smith are set to co-star opposite Robert Carlyle on Sci Fi Channel's new original series "Stargate Universe."

The series, from MGM TV, follows a group of soldiers, scientists and civilians left to fend for themselves when forced through a Stargate after their hidden base comes under attack. The survivors, who emerge aboard an ancient ship missing in the far reaches of space, are led by Dr. Nicholas Rush (Carlyle), who works to unlock the ship's mysteries and return the group to Earth.

Louis ("Hidden Hills") will play Col. Everett Young, an experienced Stargate team leader.

Blue ("Ugly Betty") plays Eli Wallace, a slacker who just happens to be an utter genius with anything he puts his mind to -- everything from mathematics to video games.

Brian J. Smith ("Hate Crime") is Lt. Matthew Scott, a junior member of the Stargate team thrust into the role of leader well before he's ready.

Jamil Walker Smith ("Sister, Sister") plays Sr. Sgt. Ronald Greer, a Marine with a temper.

"Stargate" veterans Brad Wright and Robert Cooper are writing/exec producing the series, which will debut in the fall as a two-hour movie and will be distributed by MGM Worldwide TV Distribution.
