Sorry, but that is not at all true He's made two comments. He hasn't done the show because of several reason and they are hinted at here:

Yeah, I probably should have said I was referring to the actor who played Apollo on Battlestar Galactica.
Oh,wait
I don't know what they have to say. It makes no difference anyway. Whatever it is, I'm against it.

Oh. I was going to say I haven't even heard that Survivor guy's name in like 16 years. The only reason I remember it is because of how hot that show was at the time.

Richard Hatch who played Apollo on the original Battlestar Galactica!

Richard Hatch? The old fag from the first season of Survivor?

From what I have heard, Richard Dean Anderson has publicly been trashing this show before the first episode even aired
Richard Hatch did the same thing before the new Battlestar Galactica aired, but eventually changed his mind and ended up doing 22 episodes as Tom Zarek, which is actually one more episode than he played Apollo in the original Battlestar Galactica.

From what I have heard, Richard Dean Anderson has publicly been trashing this show before the first episode even aired and continues bashing it. So yeah I doubt he will appear on it even though that would be cool.
