Other mistake: Kevin rides down the stairs on his sled and out the door. He originally lined up the sled at the top of the stairs, but it is clear that the stairs lie to the right of the door. His sled went straight down the stairs, therefore making it impossible to go straight out the door in one movement as shown. (00:25:25)
Other mistake: In the music within the ending credits, the lyrics incorrectly state that Raph is the leader of the group when all Turtle fans past and present know it is Leo.
Other mistake: When Marty returns to 1985 from 1885 the time machine is destroyed by a train. What is strange is that not only does the train not stop (which is mandatory in the event of an accident) but there is also no reaction from people nearby, such as those in the vehicles waiting to cross the track at the level crossing. Later, when Marty returns to the site with Jennifer, there is still no sign of police officers or other officials.
Other mistake: When Big Boys' men drive through the garage door trying to escape, Dick Tracy, the cops and the goons start opening fire. Yet, nobody seems to feel the need to stop and reload their weapon. They just keep firing without ever running out of bullets.
Other mistake: When Bastian and Atreyu gets to Xayide's castle, laser beams are are searching the ground for the intruders. Right before Bastian gets hit by the laser we see him running for Atreyu. Then we see light (obviously from a spotlight) being switched on and hitting the rock which Bastian jumps on. However we see the light from the spotlight move out of position as if the person controlling the spotlight thinks that Bastian will run further off the rock. When it cuts the light is back on Bastian and the rock. (00:39:00)
Other mistake: Before the Grand High Witch starts the meeting, Luke is watching the witches sit down, and he doesn't recognize the Woman in Black. This doesn't make sense because the Woman in Black attempted to kill him during the treehouse scene before any of them arrived at the hotel. The Woman in Black is even the first witch who tries to capture him when he runs on the stage.
Other mistake: Despite being Australian citizens neither McLeach nor Cody possess an Australian accent.
