As much as I dont LOVE Jack or reunion years.....I think your wrong on this.
I think it looks like a younger version of Jack. Dont get me wrong its not a great quality vid but.....The Hair is similar,just shorter or less untamed. The make-up also looks very similar, the same colors in the same areas, just not as large/out of control.
Its not the version we're used to seeing but.....it could be him. I don't think there is any evidence that it's NOT him.
Maybe this is a larger clue than we all think? Maybe we are really going to see the beginings of these characters....and Horror Nights itself. Maybe we are looking very far back into the Horror Nighhts scrap book?
This gives me hope that they might have really done something special......something better than 16...better than rehashing houses,or throwing together random crap from a whole year and calling it a house/maze.
