Corrected entry: No one in Sleepy Hollow bats an eye at Christina Ricci being a "good witch". This certainly seems unlikely given the time frame of the movie.
Corrected entry: During the fight on the carriage, everyone jumps to a horse except the Horseman. Watch as the carriage hits the fallen tree. The Horseman has his sword in his right hand. After the Horseman lifts the carriage off himself, his sword is suddenly in his scabbard. (01:31:20)
Correction: We see an axe thrown by the Horesman disintegrate after it lodges in wood earlier on. I imagine his sword is the same. If he loses it, it or just casts it aside, a new copy reappears in his scabbard.
Corrected entry: Right at the very beginning, after the Headless Horseman's first victim, the coach driver, is beheaded, Martin Landau looks out of the coach window to see the headless body 'as stiff as a board' sitting upright in the driver's seat. In reality his body would be limp and probably have slumped forwards or sideways and rolled off the coach. (00:03:00)
Correction: That's what the viewer should assume though.
Correction: We don't need to see his death. A sudden fatal injury (like, for instance, being beheaded) often produces what is known as cadaveric spasm, a tightening of the muscles that freezes the body in place. This is why many suicides are found still gripping the gun with which they shot themselves.
Correction: A body killed instantly, in shock before death is possible to enter a rigor mortis like state at the time of death.
Since Dirk's death was never seen onscreen, there's no way of knowing if he was in shock before he was killed.
I don't know about you, but if I was being chased by a Headless Horseman wielding a HUGE sword, I'd definitely be in shock.
Corrected entry: We are told that the horseman filed his teeth to a point to look more fearsome, but when we see the horseman's skull, its teeth are perfect. (01:34:55)
Correction: The skull's teeth are sharpened, as seen in 1:24:00, when Katrina's stepmother is raising the Horseman. They may have dulled from being buried underground for twenty years, but they're still not normal teeth.
Correction: She doesn't exactly parade the fact that she does spells. And during the confusion of the church scene, people were too frightened of the horseman to be noticing her.
