Continuity mistake: During the mailbox baseball scene, Ace is shown with a cigarette in his mouth. Then after he strikes out and says "ah shit, I'm out", the cigarette is gone.
Factual error: When they find the dead body, the body looks like it has been dead for only a short while, his face even had a pinkish color to it still. Factually, the body would be a lot more decomposed after a few days, bluish or white in color from the blood pooling at the bottom of the body, since the body was on its back. (01:08:30)
Continuity mistake: In the leech scene when the boys get out of the water, Chris takes off his shirt and there are no leeches on his back. But when Chris says "Gordie there are some on your back man. Are there any on mine." he has about 4 or 5 leeches on his back.
Continuity mistake: About half way through their journey the boys clothes are very dirty, then they become spotless.
Continuity mistake: When the four boys first come to the railroad, Vern shows them his comb. He is holding it upwards, then lowers it a little. Then when Gordie says "Lotta thinking Vern, thanks," his arm is straight down next to his side.
Visible crew/equipment: In a bird's eye view when the boys cross the bridge, there is a camera visible at the end of the bridge.
Revealing mistake: During the pie eating scene when the projectile stream of blueberries starts, the alignment is off for most of them, as it appears to come out of their noses and chins as well. The pie eating contestant next to the radio personality has their stream fall in an arc until it looks like it's coming from beneath their chin directly downward.
Continuity mistake: The author in the beginning is supposed to be Gordy grown up, but the grown up Gordy has blue eyes and light hair color and Gordy as a kid had brown hair and brown eyes.
Continuity mistake: At the story told by Gordie about the kid eating pies, at the last pie his face cleans up a little bit between shots.
Continuity mistake: When the boys are continue their journey the second day they are by each other eating blueberries but when it cuts Gordy and Chris are in front of Teddy and Vern while the others are both holding a string.
Revealing mistake: When Ace runs the truck driver off the road, it's obvious that Ace Billy and Charlie are stunt doubles, because of the hair and age.
Continuity mistake: In the beginning scene, the newspaper clipping under the headline shows the first sentence to be about Chris' death from a stabbing, but the next line starts mid sentence about a completely different subject and the second column under the headline talks about taxes, mentioning nothing about the death.
Continuity mistake: All throughout the movie, the angle of the sun and shadows change within scenes. Especially in the scene when the boys are near the train bridge talking. As the camera shots switch, the shadows change angles.
Continuity mistake: When the boys are in the treehouse at the beginning, the coca cola bottle on the treehouse shelf constantly moves places between shots. The two sides of the bottle saying "coke" and "coca-cola" keep switching positions between shots also. (00:02:55 - 00:04:55)
Continuity mistake: Near the start of the movie, in the tree house scene, Chris has a cigarette packet rolled up in the left sleeve of his T-shirt, the cigarette packet is seen to disappear and reappear several times during this scene.
Revealing mistake: When Davey cracks the egg, you can tell he doesn't crack it into his mouth. It slides down his cheek and hits the ground. You can actually hear this happen.
Revealing mistake: During the Barf-O-Rama scene, look and you can see that everyone is puking the same thing. No one in the crowd was in the contest.
Suggested correction: This scene is part of a fictional story being told by one of the characters; since everything depicted is taking place within the characters' imaginations, this is not a mistake.
Factual error: There's a scene with a house in the background that has the electric wires from the power pole going to a connection above the roof. In 1959, the connection would have been made under the eaves or on the outer wall.
Factual error: When the boys start their hike at the railroad yard, there is a modern transformer on a pole in the background. In 1959, they were smaller and black. (00:15:00)
Continuity mistake: After Teddy tries to dodge the train, the boys head back in the opposite direction they were walking. Not a question of camera angles. They're walking towards the oncoming train. After the train passes, they resume walking in the same direction it passed.
