Actor/Actress with the Most Impeccable "Nerd" Credentials

There's a Farscape version of D&D that I'd be willing to try, but no one probably plays it.

I've always mulled over whether or not Stargate would port to a D&D version somehow. Would be very interesting. I even played around with class and race ideas. There is way more than enough content in that universe to make plenty of modules to play.
