Continuity mistake: In the part where Tacy and Nicky have just had their big fight and Tacy is sleeping on the couch; you hear all of the train and gun sounds and Tacy jumps up to run to the bedroom shouting, "Nicky! Nicky!" she accidentally slips in a "Ricky". So her shout sounds like this: "Nicky! Ricky! Nicky! Nicky!"
Continuity mistake: Two different cars are used; a smaller Mercury and a larger more powerful Lincoln in the hill scenes - both convertibles. Side trim gives it away too.
Continuity mistake: When Nicky leaves the trailer the night before the long haul up the mountain, he is wearing a brown leather jacket. When he returns the next morning, as Stacy is supposedly getting rid of all the rocks, jams, etc., he is wearing a blue jacket.
Revealing mistake: When Nicky is taking a shower in the trailer, on two different occasions you can see the beige colored towel that is wrapped around his waist.
