The end is the beginning (of the end)
Yikes, what attention to detail. I just noticed that the zombified school bus kids who arrive at Mr. Kreeg's house in the closing scene can be seen in the background leaving that same-said house in the opening pre-title sequence at minute 3:30 (behind the three running trick-or-treaters & to the left of the guy with the white mask). I can't help but wonder what bounty they have in their bags.
