Continuity mistake: When the waitress at Dottie's seduces Butch, the degree of boob exposure varies depending on the camera angle (not only due to perspective). (01:17:15)
Continuity mistake: When they are all in the trailer chasing Butch's car, the trailer shakes and smashes about, but when you see the view inside the trailer the passengers are not even moving or anything in the trailer moves.
Continuity mistake: When Phillip is pulled into the Ford, his socks, in which he has been running around all day, are remarkable white, but later, at the Friendly store, they are as dark grey as one would expect. (00:39:25 - 00:45:00)
Continuity mistake: When Phillip drives the Ford across the meadow the way he pushes the pedals doesn't match the engine sound and the movement of the car. (01:09:10)
Continuity mistake: When Butch pulls up to stop after he punched Terry, Terry is holding his nose with one hand. When the camera angle changes he is holding both hands to his nose. (00:21:50)
Continuity mistake: When Butch and Phillip reach the end of the tarred road they stop directly in front of a signpost. Towards the end of the scene there are some shots where the distance to the post is at least five meters, and also from the position of the steering wheel one can tell that the car has been moved in between. (01:01:50)
Visible crew/equipment: When Mack talks to Butch in the cornfield a crew member is reflected in the side of the car. (01:28:35)

Visible crew/equipment: When the driver of the truck explains the intercom system to his colleague, there's a reflection of a crew member with sunglasses at the bottom of the windshield. (00:34:50)
Continuity mistake: When Phillip walks away with his mom, the dollar bills keep falling out of his costume one by one at quite a distance from the dying Butch. However, when the camera cuts to Butch the bills strangely pile up on him. (02:05:05 - 02:07:05)
Continuity mistake: After Phillip has tricked-and-treated the old lady she closes the screen door behind her. When the camera angle changes and he says thank you the screen is open again. (01:05:20)
Factual error: One character refers to the mobile command post in the Airstream trailer as "high-tech", a phrase that wasn't around in 1963; "space-age" would have been more correct for the period.
Continuity mistake: When the farmer hangs on to his car his elbow switches back and forth between inside and outside the car. (00:39:55)
Continuity mistake: When Phillip is about to leave the Friendly store he is seen from behind with his arms hanging down. When the camera angle changes he is holding on to his booty. (00:50:30)

Other mistake: When Butch steals the clothes and the Ford, Phillip pees for almost two minutes, which is OK for an elderly man with a malfunctioning prostate but not for a healthy 8-year old boy, not even after an overdose of RC Cola. (00:39:20)
Visible crew/equipment: When Butch pulls up at the farmhouse where he is going to steal the Ford, a camera is reflected in the side window behind Butch. (00:36:00)
