Stargate Universe's Brian J. Smith on fart machines and sex

Brian J. Smith, star of Syfy's Stargate Universe, dishes about the cast in the second part of our exclusive video interview, revealing who owns a fart machine and giving us his dead-on impression of co-star Robert Carlyle.

Smith, who plays Lt. Matthew Scott, also offers up insights into the future of Scott's relationship with Chloe (Elyse Levesque) as the first season resumes on April 2 at 9 p.m. ET/PT.

"With Chloe and Scott, I never really thought it was about sex," Smith says, adding: "That relationship is based on two people who look into each other's eyes ... and understand a kind of pain that very few people understand."

Stargate Universe airs Fridays at 9; it has been picked up for a second season, which kicks off in the fall.
