The whole original cast from Stargate SG-1 (Richard Dean Anderson, Amanda Tapping, Michael Shanks and Christopher Judge).
Oh my God, yes! I used to love that show so much, even back when I was too young to follow some of the more complicated storylines. It was the cast that did it for me. Unfortunately, they stopped showing it in SL after Season 1, and I haven't had time to look it up again yet.
