The following contains MODERATE spoilers for the SG-1 episode, "200."

Having left the world of Stargate Command for most of the last year, Richard Dean Anderson is coming back, according to gateworld.net.

The former series star and executive producer is set to return in the record-setting tenth season of "Stargate SG-1." Anderson will appear in an episode titled "200," which is to air this summer as the venerable series' 200th episode.

The former leader of the SG-1 team also is on board to guest star on sister series 'Stargate Atlantis' in its upcoming third season. Anderson will appear in other tenth-season episodes of 'SG-1,' as well.

"We'll see Willie Garson," executive producer Brad Wright said. "He's coming back. It's sort of a full circle thing. The story, in short strokes, is Martin Lloyd has come to the S.G.C. because even though 'Wormhole X-Treme!' was canceled after three episodes, it did so well on DVD they're making a feature. A little kiss to 'Serenity' and 'Firefly,' which was possibly one of the best canceled series in history. And we're the Air Force consultants on the script."

Garson plays Martin Lloyd, a human from another planet who hiding on Earth after deserting a war but doesn't remember it. Lloyd created the fictional TV series "Wormhole X-Treme!" based on his unconscious knowledge of the Stargate.

"So it starts with a read-through," Wright said. "But the vignettes spring from suggestions by our characters, and material in Martin's script which is kind of outrageous, too. And we jump all over the place -- I mean, we are going all over the place in this story. It's out there ... in a good way! It's fun. Hopefully it's funny. Hopefully it's very funny -- if not, it's at least fun."

Wright also said unlike Anderson's brief appearances early in Season 9, Anderson's role in "200" will be more than a cameo.

New episodes of both "Stargate SG-1" and "Stargate Atlantis" will return to the SciFi Channel in July.
