So where's Richard Dean Anderson? McGiver? Whatever?
He's still a producer on the show, and will return on the 200th episode, but he is no longer a regular on the show. I think he wanted to spend more time with his family.
As Panerai indicated Jack is back for episode 200. They approached him about doing a bit and he not only accepted but let it be known he'd come back for more occassional episodes if they could work him into the plots without disrupting stuff. He still wants to live in California with his family, but he's open to four or five episodes, at least according to the original news item on Gateworld.NET.
And "200" looks like it's going to be a riot. They're going back to what they did for episode 100, a TV show inside the TV show called "Wormhole X-Treme!" The episode spoofed all of the goofy things about science fiction. My favorite was the actress (in the show within the show) who asked "OK, I'm out of phase, so I can walk through walls, right?" and when they said yes she said "So why don't I fall through the floor?" They all looked at each other and said "we'll have to get back to you on that."
They let basically everybody on the show (the real show) contribute little bits of business and different plot elements. It was very funny. I'm really looking forward to "200".
