Okay I felt like this deserved its own thread just to draw attention to it. I am sorry I didn't start this sooner. Here is the guest list so far with more, like Dylan Neal, still being added.
Julie Caitlyn Brown
Robin Atkin Downes
And I don't see him listed on the Space City Con website, but trusted sources say Marshal Teague will be there. I really wanted the show to continue with him in the role of Ta'Lon. I so wanted to see where that character's story went.
