Continuity mistake: In the flashback to the death of the headless horseman, when the horseman's steed gets shot and falls to the ground, the blood and the wound are on the right side of the horse...later in the scene when the horse is seen again, the wound is on the left side of the horse.
Trivia: Numerous references to other Tim Burton films: a) The dress Katrina Anne Van Tassel wears at the end is similar to Beetlejuice's outfit. b) Crane has various sharp scissor-like tools, which is a reference to Johnny Depp's early film "Edward Scissorhands" (1989). c) The scarecrow at the beginning looks exactly like Jack from "The Nightmare Before Christmas" (1994). d) The covered bridge is a lot like the bridge in "Beetlejuice."
Continuity mistake: In about the middle of the film where Ichabod Crane is writing doing process of elimination. He writes "Baltus" in cursive. Watch the tail of the "s" on "Baltus." One or two shots after that the "s" on "Baltus" is clearly different than the one we watched him write. The "l" in Baltus changes too.
Continuity mistake: At the church scene, the Horseman hauls a piece of fence through the church window and through Christina Ricci's father. After much screaming and amazement, the old man is ripped back through the window. However when he is torn from the church back out the window, the window breaks before he hits it. And wouldn't some of the window have broken when the spear was thrown through in the first place? We don't hear breaking glass or see any broken window panes.
Continuity mistake: When young Ichabod jumps back from the sight of his mother in the iron maiden, he punctures his hands on a spiked chair. The hand area of the chair shows approximately six rows of four spikes and would be very hard for his small hand to have gotten more than seven or eight punctures at the most, rather than the twenty or so he sees on his hand after he wakes up.
