Trivia: Jimmy didn't die even though it never shows him after he faints on the steering wheel in the car with Lori. He simply passed out. The television cut shows him alive in the ambulance at the end, but for some reason in the theatrical version, they left it out for us to 'wonder'.
Trivia: Teddy Lewis tells Ned that "Matty" had him show her how to rig up a explosive with a delay to a door. So in theory Matty could have opened the door and escaped unscathed.
