Continuity mistake: All four guys are in the junk-yard and they are all about to toss their coins to see who goes to get the food. When Teddy throws his coin in the air he is wearing no dog tag necklace but when he catches the coin he is suddenly wearing the dog tag necklace. (00:22:15)
Continuity mistake: When the boys get dunked in the swamp, Teddy takes his glasses off, but then while they're thrashing around in the water, both hands are clearly empty. Then, when they get out, he has his glasses in his hand again. (01:02:05)
Factual error: After Wil Wheaton fires a warning shot, he points the pistol at Kiefer Sutherland and pulls the hammer back to threaten him. However, this is a semi-automatic pistol, and the hammer would already be cocked after the shot he fired. (01:13:40)
Continuity mistake: The amount of blueberries and sauce on Lardass Davey Hogan, before he vomits, changes from shot to shot. (00:46:10)
Continuity mistake: When Gordy returns to the junkyard after getting the food he sees his friends running away. The junkman yells at him and Gordy starts running away towards the fence. In the background he passes the same junk vehicles multiple times. (00:26:15)
Continuity mistake: When the boys are at the junk yard and they nominate Gordy to get the food, when Gordy jumps up and starts joking with the boys, Vern and Chris start to fight. Then the shot changes and suddenly Teddy, who was off to the side, is in the middle of the pile. (00:23:35)
Answer: No, it wasn't that big of a train. He didn't even attempt to get off the throttle. That's all it would have taken for the boys to make it fairly easy. It was a straight-away track, no chance of it derailing by hitting the brakes. Like the man said above, if trains derailed that easily, we wouldn't be using them.
