With filming on Stargate Universe – the latest spin-off from the 1994 Stargate movie – shortly to commence in Vancouver, Sci Fi Channel has released details of four further cast members joining star Robert Carlyle.

Saw IV and V's Justin Louis will play Colonel Everett Young, an experienced Stargate team leader, alongside Moonlight and Ugly Betty's David Blue as Eli Wallace, described as a "slacker who just happens to be an utter genius with anything he puts his mind to".

Hate Crime's Brian J. Smith is Lt. Matthew Scott, a junior member of the Stargate team who's given responsibility long before he's ready for it. Jamil Walker Smith, who appeared in both the Supernatural and Medium pilots, will play Senior Sergeant Ronald Greene, "a Marine with a temper."
