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.
