During a flashback sequence that takes place in 1955, teenagers are driving around in a convertible as Jerry Lee Lewis's "Great Balls Of Fire" blares from the car radio. Lewis recorded, and released the song in 1956, one year after the events depicted in this scene take place.
One man buys a first edition, signed copy of "Treasure Island" by Robert Louis Stevenson. In later scenes, he and the little girl who stole it refer to the title as "Huck Finn" by Mark Twain. In the video and DVD release, his words are dubbed over to correct the mistake. On the television broadcast, the mistake was not corrected. This is an audio mismatch and a continuity error, depending on which version you saw.
The character Frank Jewett buys the First Edition of Treasure Island in the shop. Later in a fight with Sheriff Pangborn this mentioning of the book's title is dubbed as Frank seems to have bought something else than the Treasure Island. When it comes to the mentioning of the "First Edition" of it, the dubbing is correct again.

When she introduces herself to Mr. Gaunt, she says she doesn't shake hands; later, she is unable to put on the silver charm; and the degree of her pain is frequently alluded to in dialog. However, she is shown carrying a nearly full coffee pot, carrying a cup and saucer, holding a phone receiver: a person with advanced arthritis would be unable to do any of those things.
When the shop explodes at the climax of the movie, Reverend Rose and Father Meehan take shelter behind a gravestone in the churchyard. The stone wobbles back and forth when the priest's shoulder bumps it.
