Other mistake: While touring the dam, Catherine (Ellen's cousin) mentions that Eddie told her that they'll get electricity some day. But earlier, we saw a working refrigerator (with a light that went on and off) in the trailer's kitchenette. When Eddie and Clark are digging for the buried money at night, we also see lights on the trailer's exterior.

Continuity mistake: Early in the movie, when Kevin Bacon and Josh Brolin begin to chase Isabel (the invisible gorilla) down the hall, Kevin does not have any special goggles and didn't grab any when he got the gun. This is confirmed when we see the backs of their heads as the chase begins. When Kevin catches up with Isabel, he brings down his goggles from the top of his head as if he had them all along.

Continuity mistake: The small plane's pilot identifies the aircraft as 232Z. But in the exterior shots, the aircraft's identification is N9750Y. (00:35:00)
