Other mistake: The guy says "looks like I'll have to send more flowers" then opens up the activation card and code to destroy the building. The code is 50617 but he swipes the card then pushes 50671. (01:00:00)
Suggested correction: If you watch the keys again he presses the exact appropriate numbers in order. 50617.
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: When Woods gets shot by the nails fired by the small robot, the amount of blood in his sweater keeps changing during the following scenes.
Other mistake: When Evie is in the library and all the book cases start to tumble over, if you look at one of the corner book cases you can see a piece of paper landing on it and the books are clearly painted on a flat piece of cardboard. (00:13:30)
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: Toward the end of the movie, as Johnny Depp and his leading lady are being led down into the dungeon, you can actually see the camera bouncing and shaking and hear it hitting the stairs as it moves down the stairs.
Other mistake: Nell's hair is considerably lighter in the scene where it starts moving by itself - clearly CGI.
Other mistake: When he is talking to his sister in-law during work on the phone, the red wire, which was connecting them so they could talk, dropped or fell out of place. Even though this happened, the conversation still continued.
