Continuity mistake: In the scene where Thor tells Jane to hold on, she's on Thor's right side and Mjölnir (the hammer) is in his left hand. As they are traveling through the Bifröst to Asgard, the position of each has changed. (00:28:20)
Continuity mistake: When the Enterprise is spinning out of control, Spock and Sulu activate their seat belts across their shoulders, but Sulu's disappears shortly afterwards, only to reappear seconds later. (01:41:05)
Continuity mistake: When Jack sets up the motorbike, he pivots the two bars forward and locks them to form the handlebars. A few shots later as Jack looks down at the sensor, you can see one solid handlebar, all the way across. (00:13:45 - 00:14:25)
Continuity mistake: When young Clark saves the school bus and is watched by Lana, his fringe swaps from being brushed to the right to brushed to the left, between shots. (00:27:55)
Continuity mistake: When Gipsy Danger is lifted by the Kaiju in Hong Kong, they end up well above the clouds, and when Gipsy falls she eventually breaks through them. But in the shots when she is falling, you can see that there are no clouds around Hong Kong for miles. That, and Pentecost has a clear view of Gipsy through his binoculars.
Continuity mistake: Young Dan and Jo are fighting over their meal. The position of the tray on the table changes several times, most noticeably when Dan leaps off the table. Moreover, when he returns to it after he jumped off the bed, the tray is empty minus a little red berry, but it still had rice and other food on it earlier. (00:18:30)
Continuity mistake: In Kandor, Superman punches a hole in the ground and picks up a large chunk of the street out of the hole, but does not move from that spot. The shot changes to the robot's perspective of him about to throw the rock and shows his feet. The ground he just punched and picked up is in perfect condition at his feet. No hole, no cracks, no sign of the damage he just made. (00:41:15)
Continuity mistake: As in most movies I've seen where size is a main factor, the animators did not pay much attention to scale. In the scene where the main character leads the leaf people to her father's house, she is jumping and lands on the thinnest pencils I've ever seen. They have the width of the pencil smaller than her foot. However later on, it is shown that a push pin is almost the size of her body.
Continuity mistake: When Billy pulled the medallion out of the ground, part of the cloth covering it was hanging past his hand, but when he blew dirt off the cloth, the cloth was compactly covering the medallion. Also, the cloth should have had more than some loose dirt on it and the medallion - after buried in the ground for 200 years - should have been dirty and tarnished, not clean. (A cloth covering the medallion would not protect it from soaking rains). (00:23:35)
Continuity mistake: Juliano and Joaquin are having their pictures taking celebrating the first earnings from their own gold pit. All of a sudden between shots, the photographer loses the cigarette behind his ear. (00:18:50)
Continuity mistake: During the first meeting between Sebastian and Belle, the dog drops the game far back on the hill, but the rest of the scene takes place with the dead hare right in front of the 'beast', on the edge of the rock. (00:10:10)
Continuity mistake: When the police officer picks up Woody, he is wearing boots. In the police station, he is not wearing boots. (00:01:05 - 00:02:25)
Continuity mistake: In "China", when the trackers and the hunters are walking through the forest at night, between shots, the group goes from five people to four people back to five people. (00:30:46)
