Brad Wright, co-creator of SCI FI Channel's upcoming Stargate Universe, told Gateworld that Stargate SG-1 star Richard Dean Anderson ("Jack O'Neill") will guest-star on the new show. SG-1 cast member Gary Jones ("Walter Harriman"), meanwhile, told fans he would also appear in the new series.
"Rick is doing episodes of Universe," Wright told GateWorld. "He was just here yesterday shooting an episode of Universe with us. So that relationship is always ongoing, and it's good to have him back."
The show's fifth episode, "Earth," is currently filming and is likely one in which Anderson will appear.
For his part, Jones appeared on stage at Creation Entertainment's official Stargate convention in Vancouver, Canada, and told fans that he is appearing in an episode of Universe with Anderson. He said that Gen. O'Neill will have been promoted to three-star general for the episode they filmed together.
Jones added that he was asked to appear in the Universe premiere, "Air."
Stargate Universe—a spinoff of Stargate SG-1 and Stargate Atlantis—follows the adventures of explorers who start off on a reconnaissance mission to the Destiny, a ship built by the Ancients, only to wind up on a never-ending mission when the crew learns the ship can't return to Earth.
Stargate Universe will premiere later this year and stars Robert Carlyle, Justin Louis, Brian J. Smith, Alaina Huffman, David Blue, Ming-Na and Lou Diamond Phillips.
