I wrote an email to FX and Megacon asking them to consider inviting some of the lesser known BSG actors. Hot Dog, Kat, Racetrack, etc. Fx was very nice and said they will try to do what they can and they hinted at some big Heroes stars. Someone else I know confirmed they're trying to get the guy who plays Hiro. If they do, I'm buying a replica sword for him to sign!
Megacon was not so nice. I got a very curt reply about how they already have Anne whats-her-face who is one of the original BSG actors. blah blah... I could really care less about some woman who played a viper pilot on the 70's hokey pokey show.

They also have Mark Sheppard, but I've already met him.
