Continuity: Teddy's hair changes in every shot after being dunked in the swamp. The strap to his bag disappears and reappears as well.

Continuity: In the beginning he mentions Teddy's left ear being burnt by his father on a stove. Notice how his ear goes from looking severely burnt, to not burnt at all, through the movie. Especially the water dunking scene.

Continuity: 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.

Continuity: When the boys are dunking each other in the swamp Gordie starts to wade away, when he passes the camera his hair is dry but when he reaches the bank it's wet again.

Continuity: When Gordie shoots the garbage cans and runs off, he's still running when they get around the corner and he's not holding the gun anymore. He wouldn't have dropped it because it's in later scenes, and he didn't have enough time to put it in his backpack or give it to Chris because they were trying to get far away from the back of the diner.

Audio problem: At the beginning when Vern comes to the tree house to share his exciting news, when he is climbing up to get inside his lips do not match what he is saying.

Continuity: 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.

Factual error: When the two drivers of the teenage gang are playing "Chicken" on a straight section of a two-lane highway, the center lines of the road consist of yellow hashmarks. Though the picture was set in 1959, center lines for passing zones on two-lane highways were painted white until 1971.

Continuity: 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.

Factual error: Teddy wears army boots that did not exist in 1959.

Revealing: When Lardass pukes on the guy to the left of him, he moves his head prematurely, and you can clearly see that the puke is coming out of a jet positioned behind his head.

Factual error: Near the end of the movie, when the boys return to town, a garage door in the background is a modern metal roll-up type that was not available in 1959.

Continuity: When Gordie jumps over the fence away from Chopper and they all realise he's not fierce, the boys start to tease him. While Teddy's saying "Bite my ass, Choppy" the dog bites through the fence and Teddy pulls away, and then in the next shot he pulls away again and jumps differently.

Visible crew/equipment: Part of a fluffy boom mike is visible at the top of the screen when they are arguing about crossing the bridge. [Edited in DVD]

Visible crew/equipment: In the scene just after the train dodge attempt by Teddy, you can see something white hanging out of Verne's pants as he walks onto the tracks.  It is probably some part of equipment for his mike.

Continuity: When the four are deciding whether to cross the swamp, Chris pulls off a nearby tree branch to test the deepness. First the branch is quite flimsy and has two ends like a "Y" shape, and then after Chris pokes it into the marsh it becomes thicker with no split end.

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, the hammer would automatically be in the pulled back position after the shot he fired.

Continuity: In the tree-house scene near the beginning, the sleeve on Chris's t-shirt changes from being rolled up to rolled down. The most noticeable example of this is when they lift up the table to let Vern in and it cuts from a close-up to a wider shot.

Continuity: When the boys are up in the treehouse at the start of the movie, at one point Chris blows out some smoke into a cloud in front of him, but in the next shot it's completely disappeared.

Continuity: The train on the bridge is producing black smoke from its funnel, but in one shot it is producing white smoke.
