Continuity mistake: When Marty returns to 1985, he goes to his house and gets in his Toyota pick-up. Look closely behind his head when he first gets in the truck, there is no driver-side head rest. But when he picks up Jennifer, when they pull up to the stop sign the head rest is there. (01:45:00)
Continuity mistake: Near the end of the movie, when Snow White has already been tied up by Lord Malice, the Dwarfelles come to rescue her. As the Dwarfelles are beating up Lord Malice, there's a quick shot of Snow White again and she is untied and has her hands covering her cheeks. Next shot, the fighting between the Dwarfelles and Lord Malice continues and Snow White is again tied up.
Continuity mistake: When the Jetson family leaves Earth and is headed towards their new home for the rest of the movie, George and Jane switch places when Jane leans over to kiss George.
Revealing mistake: There are a couple times you can see the tape that marks where the actors are supposed to stand in the shot. In the beginning, when Bobby and his brother walk in on Ernest trying to get a cleaning machine to work, look on the floor and you will see some tape in the shape of a T. Bobby will move his feet to the T. Also when a criminal begs for Nash's help because he killed someone, and Nash walks forward, look on the floor to see another tape T, and what do ya know, Nash stops right on the T.
Continuity mistake: As Clara is asking Drosselmeier how old his nephew is, the shot is a close up of her face and at the very last frame of the shot, she is wide eyed looking up with a curious expression on her face and mouth. The shot changes to show her and Fritz, and suddenly her head is tilted down, her eyes looking differently, and her mouth showing a smile. (00:03:00)Quantom X
