I never heard of that convention either. I'm not sure if there's one comprehensive site that lists all kinds of fan conventions because there's so many different ones out there, from horror to sci-fi to generic movie ones or ones themed after just a particular movie or T.V. show.
Some of the ones I've gone to in the past are Chiller Theatre, Monster Mania, Big Apple Con, NY Comic Con, to name a few. But I've also been to some Rocky Horror Picture Show conventions, etc.
But keep in mind, sometimes guests cancel at the last minute, so you gotta bear that in mind for making plans to go to these things. My new rule is I don't go now unless there's at least 3 people I want to see so that if one or two cancel, the whole day is not a let down.
