Continuity mistake: When Sam arrives home after the baseball game, she tucks her hair behind her ear twice between shots.
Continuity mistake: When the four girls are back at the graveyard for the third time trying to talk to Dear Johnny and put him back in his grave, they see the lights and the headstone float out in front of them, with nothing holding onto it. Then in the next shot there are chains around it, from the tractor that is holding it in mid air.
Other mistake: Watch when the bird poops in Chrissie's hair. From the camera angle above them, you can see that Chrissie not directly underneath where the bird is perched. The next shot shows the bird poop falling directly below the branch. The next shot after that shows the poop in Chrissie's hair. Judging by the position Chrissie was in, in relation to where the bird was, this is impossible.
Visible crew/equipment: Chrissy sees the People magazine with Teeny's pic on the cover and asks Roberta why people get so excited over Teeny. When Roberta answers straightforwardly, in the next shot the shadow of the boom mic can be seen moving over the fridge, at the top of the screen. (00:05:40)
Continuity mistake: When Roberta falls over on the road after missing her dive onto Scott on his bike, a man ahead with a briefcase hurries across the road before one of the other Wormers can cycle into him, and another one of the Wormers cycles ahead of him. After Roberta vows revenge on the Wormers, and when Scott yells back at her, the man is seen crossing the road again at a steady pace with all four of the Wormers coming before him.
Continuity mistake: In the beginning of the movie Chrissy is curling her hair, her hair remains tightly curled while in the house. When she goes out to greet the other girls her hair looks brushed out, definitely not tight curls. Then, when they all go inside, her hair is back to tight curls.
