Corrected entry: When Brad and Janet's station wagon gets a flat tire, the light in the car is a bright white that is emanating from the floor (note the shadows above them and the ones on their faces). If the light was from the dashboard or dome light, it would be more yellow and cast downward shadows on their faces.
Corrected entry: I am not sure if this only happens only in the DVD, but at the end when all of them are dancing Columbia's boob pops out and she keeps dancing like that.
Corrected entry: With seconds to go before the castle takes off like a rocket and disappears, Brad and Janet carry the lame Dr. Scott out the front door. After the house disappears, we see pieces of Dr. Scott's wheelchair among the rubble. Did they really push the wheelchair out the door before getting out themselves, with their lives at stake and almost no time to spare?
