Continuity mistake: When Hallie and Annie are in the isolation cabin, you see the bucket that the water is dripping into from the leak in the roof, on a stack of books. After the wind blows all of Hallie's pictures off the wall they are sitting on the ground picking them up, Annie is seen picking up Hallie's little animal (Cuppie) right next to the bucket of water, which is now on the ground with no stack of books to be seen.
Continuity mistake: When Annie and her friends are approaching the area where the fencing is taking place, all three girls are holding tennis rackets. The shot switches to the camp counselor and back to the girls. The African American girl is no longer holding a tennis racket. The shot goes back to the counselor and then to the girls again, where all three have a tennis racket again.
Continuity mistake: When Hallie (posing as Annie) arrives in London, she is seen sitting on the left seat in the car when she's on her way home, passing by the various spots in London. However, when she reaches home, she is sitting on the right side of the car. Unless she was sitting alone, this is not logical as Martin was sitting together with her at the back of the car.
Continuity mistake: When Annie and Hallie are just about to play cards, Annie spreads all the cards out on the bed and turns them over and then back again. But in one of the shots you can see that it is Hallie who turned the cards over because her fingernails are painted and Annie's are not.

Continuity mistake: In the opening scene, they show the lake and the little sign that says Camp Walden. There are boats under a roof top right in front of the pier. But in the scene where they show Annie jumping into the lake the boats are in a different location and the roof top is gone.

Continuity mistake: In the opening scenes where they show the camera girl about to take a picture of them, you can see that there are candles and a flower arrangement on the table. When they open the book to show us the picture of them the candles are gone and the flower arrangement is different.

Continuity mistake: When Hallie is posing as Annie and is going to her mother's house for the first time, a piece of her hair is obviously sticking out on the side of her ear (It's very noticeable). When she gets to the front, and the camera angle changes, her hair is all perfect without any hair sticking out.
Continuity mistake: When Hallie and Annie drag Meredith into the lake when she's asleep on the air mattress, the color of the air mattress is dark green. When Meredith wakes up with the bird on her chest, all of a sudden the air mattress is a two tone khaki color. When Meredith stands up on the air mattress in the next shot on the lake, the air mattress is now another shade of green.
