Indeed, there are folks about like that. As far as I'm concerned, as long as they're happy, and not harming anyone else, I don't have a problem with them, but, I certainly wouldn't want to be one of them, as I've heard a few, well, not 'unpleasant' things said about them by actors, but, let's just say the actors don't always share the enthusiasm of the fans over their 'devotion' to the subject I think the actor with the best attitude towards such fans, is Wil Wheaton. I've read blogs where he's reminded other actors that it is those 'freaks' who put them where they are, and without them, they'd have nothing. A very smart, very humble and down to earth guy. As I said above, I draw the line at costume parties, although I'm sure the cons are great fun
