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: 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: 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.

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.

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

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]

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 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.

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

Visible crew/equipment: A reflection of a camera tripod can be seen in Teddy's glasses when Teddy and Chris are arguing on the railroad tracks.

Revealing: In the train scene, River Phoenix's voice has suddenly changed and he looks older. This scene was obviously shot last, and he has started going through puberty. But in terms of movie time, he has gone through puberty in two days.

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.

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.

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: In the first shot of the scene where Gordie has a flashback of his family at the table, we see two pieces of corn near his plate. In the next shot of Gordie's plate, the pieces of corn are gone.

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: 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.

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.

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.
