Corrected entry: When the 4 crawl soaking wet from the swamp and pull off the leeches from their bodies, they begin to put their clothes back on. Suddenly, their clothes and themselves are bone dry. (01:04:45)
Corrected entry: When Chris shows Gordie his gun he states that it's a colt .45. At the end of the movie, Gordie fires it once, then cocks the hammer for a second shot. A colt .45 should do that automatically.
Correction: Earlier on in the film he also states that the gun is unloaded, and it turns out that it isn't. It's likely that he got the name of the gun wrong as well.
Corrected entry: In the scene where Gordie "notices" the leech on Vern's neck, he was in no position to see it, as he was being held in some sort of neck hold by Vern, with Vern directly behind him. You can see Gordy turns his head to somehow make us believe he can see the leech, but it would have been physically impossible.
Correction: Just watched this, it's never revealed how much time had passed. They could have spent an hour waiting for clothes to dry out and Gordie to recover from fainting.
