Revealing mistake: When Sarah defeats Jareth, you can see levitating arches in the background. If you look closely at them, however, you can see the wires holding them up.
Visible crew/equipment: When Newton is playing with the robot arm and the piano you can clearly see wires attached to the top of it controlled by the puppeteers.
Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Continuity mistake: The band-aid on Jill's doll disappears and reappears several times.
Continuity mistake: In the battle scene at autobot city, Megatron orders Soundwave to jam the transmission that Blaster is sending to Optimus Prime. When Soundwave ejects Rumble, Frenzy, Ravage & Ratbat we see them flying through the air transforming simultaneously and and both Rumble & Frenzy are coloured the same (red & black) when Rumble is supposed to be purple. (00:15:08)
Revealing mistake: When Ratigan is sneaking up on Basil inside Big Ben, there is a shot where both characters have their backs to the camera. In this shot, there is a piece of equipment directly in front of the turning gear they are standing on. This piece of metal can be seen to flicker for a few moments.
Continuity mistake: In Dark Heart's cave, when all of the Care Bears are locked away in cages, one of the star buddies tries to pry open a cage's lock with its right arm. But as soon as three of the trapped Care Bears are released, the star buddy's left arm appears mangled instead. (00:55:55)
Continuity mistake: In a matter of 15 seconds between David's ship exiting the hangar and shooting 20 miles upwards into space, shadows on the ground indicate very different positions of the sun. (00:51:05)
Continuity mistake: The film is supposed to take place in 1917, but several of the german soldiers our heroes encounter are armed with Bergman M18 sub-machineguns which didn't appear until a year later. To make things even worse all the guns comes with a magazine-type that didn't appear until the mid-thirties.
Continuity mistake: When Tiger and Fievel are doing their musical piece, Tiger wipes off the mirror and they appear the same size. When he lays out in front of the mirror, singing the line "We'll be there to pick each other off the floor", he places his head next to the cage bottom, still laying on the floor between them. In the mirror, however, that cage bottom is not reflected at all. (00:57:30)
Continuity mistake: The group who set out for Flutter Valley are chased by Ahhg the giant spider after tickling him and slipping away unnoticed. As they make a dash towards a nearby cliff, Gingerbread (white Pony with purple, pink and blue hair) and Baby Lickety Split (light purple with pink hair) have somehow joined the group, but Baby Lickety Split should be with the Grundles and Spike and Gingerbread should be back at Paradise Estate.
Other mistake: How does Dola know that Sheeta's pigtails were shot off? They had been outside in their aircraft the whole time and once Dola got Sheeta in a tight hug, the situation doesn't call for any time for her to explain what happened.
Continuity mistake: In the scene where Steph is in her second show, there are at least 2 different horses. The manes and tails go from being braided to being unbraided. Also, the breeches change from grey to beige. One of the horses before her round, a chestnut, has one sock, then none, then three, etc. There were multiple (I counted at least 7) horses that played the part of Lightning, who was supposed to be registered with the Jockey Club, which is the Thoroughbred registry. Most of the horses that played him were not even close to being Thoroughbreds.
Continuity mistake: In the dinner scene the boom mic drops into view for about two seconds.
