I love it for some reason when cons invite a media guest because of a genre project they did, but you really know them for something else. Take Corin Nemec over here. Sure, Megacon might have him as a guest because he was on “Stargate SG-1,” but dude, he’s Parker Lewis! Just like Neil Patrick Harris is always going to be Doogie. They’ve also got Christian Campbell from “Supernatural,” but as far as I know, he wasn’t the lead in any early 90s teen comedies. I guess he did an episode of “Degrassi High,” but that’s not quite the same. Megacon also posted an updated floor plan, but again, the floor plan was never on Fox.
