We don't know what Stargate mythology would be without the Four Great Races, and one of those Races, the Nox, was represented early on in the show's run in an episode of the same name. Ray Xifo, "Opher" of the Nox, and a close friend of his Nox co-star Armin Shimerman, joins Dial the Gate LIVE to discuss his career and his experience as a member of this enigmatic race.

Before she was the President of the 32nd Century United Federation of Planets, she was piloting USAF ships in the Milky Way, as well as other roles in Stargate! We are so pleased to welcome Chelah Horsdal to Dial the Gate to discuss some of her most recent work, and to take us back to the days of the SG franchise.

Why, look, everybody! David's got Coombs with him! Whether or not you worship at the altar of Roddenberry, we're sure you will enjoy our LIVE interview with John Billingsley. Not only will we be discussing SG-1 Season Six's "The Other Guys" but also Enterprise, The Man From Earth and John's further career.

Before he became Carl "Helo" Agathon in the re-imagined Battlestar Galactica, one of Tahmoh Penikett's early roles in television was as the Replicator Third in SG-1 Season Six's "Unnatural Selection." We are delighted to welcome him to our show to talk about his brief time on Stargate, as well as his broader career in some of the best television ever created.

Douglas McLean, Stargate SG-1 Art Director From Season One to Season Five, joins Dial the Gate in a PRE-RECORDED interview to reveal insights into some of the franchise's most iconic sets (including some rarely-seen original set photography)!

For nearly every season of Stargate on television, Norman John Smith was quietly working away to make sure production never stopped moving on the franchise. We are proud to host the executive producer on our show and to hear stories from making SG-1, Atlantis and Universe on-time and on-budget -- as well as the story for how the Continuum Arctic shoot became a reality!

From Season Two to Season Six of Stargate SG-1 Lynn Smith served as Location Manager for the series. This included scouting, negotiating with local home owners and businesses for filming, noise issues with P-90s, and everything else involved in turning Vancouver into Colorado or another planet. She sits down with Dial the Gate to talk about her amazing six years, as well as a trip to the Arctic to film Stargate Continuum!

It's been a minute since we had the pleasure of talking with Corin Nemec, who has been busy with film projects as well as his new book, "Creating a Character for the Stage or Life." He's back to talk about all of the above as well as more memories from the production of Stargate SG-1 -- and take your questions LIVE!
