Other mistake: During the scene where the Japanese are being rounded up and taken to the internment camp, the camera is panning over the crowds of people walking down the street. Half way through this scene, there is a woman and a little girl, who seems to be carrying a stuffed Elmo, hardly appropriate for the time period.
Other mistake: When Carter is sitting in front of one of the small hatch-like doors around the time that they were climbing the ladder to escape from the rising water, one can clearly sea that the door is no more than twice the width of Carter (4 feet at most) yet the 45 foot shark about 10 to 12 feet wide seems to have no trouble squeezing through. (01:01:40 - 01:04:20)
Other mistake: Near the end of the movie, Ichabod, Katrina and the young boy are in the old windmill when the horseman arrives. When the three good characters jump onto the moving sails Ichabod drops a lantern down to the floor setting the whole windmill on fire. He, the little boy and Katrina jump off the sail onto the ground and start running back to their carriage some yards away. A camera shot shows the top of the building explode and we see a very quick shot of the whole windmill exploding in flames, but Ichabod, Katrina and the little boy have disappeared. Two shots later they are still running to the carriage. (01:30:25)
Other mistake: During the scene where the Asian man is fighting off a security guard, the guard kicks his head back one time when no-one appears to have hit him.
Other mistake: On two occasions in the movie, Ashley Judd slams a car into another (she drives Tommy Lee Jones' car into another and over the side of the ferry boat, and later she smashes a stolen pickup truck into the side of a car). In each case, the car she is driving emerges from the crash without a scratch on it, not even a damaged headlight.
Other mistake: In the scene where Cuba and Skeet are "negotiating" with the federal agent at the end of the movie, Cuba interrupts Skeet by saying, "I'll handle it from here sweetdick." Notice that Skeet almost breaks character due to an apparent ad-lib by Cuba.
