Continuity mistake: When Lois is sneaking up to the door of the school bus, you can see the front wheel appears to be one solid piece all the way around and in the spokes and center. But a bit later as she is leading the children off the bus, there are now gaps between the spokes and the center is hollow. The wheels change several times in this scene. Also the front bumper suddenly becomes elongated. The headlight is also missing from the first shot and reappears. (00:36:05)
Continuity mistake: After the police leave, Toyman moves his spider away from the bus and partly hangs off the building taunting the cops. It then cuts to a behind view of the spider, and suddenly it is much closer to the bus again, and is not hanging off as far. (00:36:05)
Continuity mistake: When Lois is sneaking up on the bus, you can see there are several pipes on the roof of the building they are on sticking up all around. But a little later when Toyman is lifting the school bus with the spider, the roof is visible behind it and the pipes are gone. (00:36:05 - 00:37:30)
Continuity mistake: Once Lois gets on the bus, the kids sit up and look at her. It cuts to a view of Lois, and behind her in the rearview mirror you can see the children reflected. Pay attention to the two on the far right of the reflection. It then cuts to a close up of them, not the reflection, and suddenly the little girl instantly has her hands over her eyes. (00:36:15)
Revealing mistake: When Lois looks in the driver seat of the bus, there is a mechanical doll there that turns its face towards her and holds up a kitchen knife. The doll has a missing eye, and this is shown in the reflection on the knife. But the crack that is under the hole where the eye is missing is not fully reflected. (00:36:20)
Continuity mistake: Lois grabs one of the three red backpacks from the front of the bus and smacks the doll with it. The backpack then just completely disappears. It's not in her hands, it's not back on the hook, it's not on the floor, nor on the ground outside of the bus. It just vanished into mid air after she hit the doll and is never seen again. (00:36:25)
Continuity mistake: When the doll leaps at Lois with a knife, she grabs one of three reddish pink backpacks and smacks it into the window. The back pack she grabs is the one on the left, and as she grabs it you can see that the middle backpack has a rectangular shape on the front that is just an outline, and the backpack on the right has a similar spot but is round and yellow. Then when the children are getting off the bus, the remaining two backpacks are shown hanging there still and the one that was in the middle now has a yellow oval shape on the front instead of the rectangular outline. The design of the backpack is also different. Also in the shot just before this, the same spot is shown, but the backpacks are missing. (00:36:35)
Continuity mistake: Lois uses a backpack to hit the doll with the knife. It hits the windshield of the school bus and falls to the ground, glass all around it. When Lois steps on it to break it, the glass around it vanishes. (00:36:45)
Continuity mistake: After Toyman's spider slashes through the seats on the right side of the bus (from the bus' perspective), then slashes and hits the seats on the left. But in the immediately following shot, the leg of the spider busts through one of the back windows on the left side of the bus, and you can see the top of the back seats sticking up in view in perfect condition despite in the previous shot being cut in half. (00:37:15)
Continuity mistake: Once Toyman throws the bus off the roof, you can see the police cars on the street below and how they are arranged. It then cuts to a view from inside the buss at Lois and the little girl hanging on for dear life and out the back window of the bus you can see the police cars. Only the ones visible are not in any way like the patterns you could see previously. They rearranged themselves. (00:37:35)
Continuity mistake: Trying to kill Lois and the little girl, Toyman uses his spider mech to slice the seats in the school bus in half. But when Superman catches the bus and sets it down safely, the seats are just fine, not cut or damaged at all. (00:37:50)
Continuity mistake: After Superman apprehends Toyman, he sets down and the police lead the villain away. A cop walks up to Superman and says thanks, Superman turns and looks at him with a straight face. It then cuts to a close up of Superman's face and instantly he has a big smile on his face. (00:38:40)
Continuity mistake: A black cop thanks Superman as some white cops lead away Toyman. Then Superman lifts off to fly away and a shot from a different angle shows the black cop suddenly vanishes. (00:38:45)
Continuity mistake: After Superman rescues Lois from Toyman, he is flying her back to her apartment. She is marveling at how he could be back and places her hand on his cheek, with her wrist going over his chin as he frowns. It cuts to another angle, and suddenly her hand has moved back some and her wrist not over the front of his chin. And Superman is suddenly smiling. (00:39:10)
Continuity mistake: As Superman is returning Lois to her apartment after rescuing her from Toyman, he goes to land on the balcony outside her room. It is first shown as small with only a table and one plant on it. But as soon as Superman lands, it is suddenly a lot bigger and a lot more stuff is on it. (00:39:25)
Continuity mistake: As Superman is saying to Lois that he will see her soon, the buildings can be seen behind them in the close up. It cuts to a far shot before he lifts off and the building that is seen above Lois' head, the windows and lights change position. The building behind Superman's head also changes slightly and becomes more symmetrical. (00:39:50)
Continuity mistake: After their awkward goodbye when Superman leaves Lois on her balcony, her hands are at her side. It then cuts to a front shot and suddenly she has her hands crossed in front of her. (00:39:55)
Continuity mistake: The live news broadcast of Superman's interview after his resurrection shows it broad daylight in Metropolis. When Martha Kent sees this at her farm, although being in the same state, it is pitch black night time outside at her house. (00:40:10)
Continuity mistake: The day after his ‘resurrection', Superman is standing in Lex's office looking for him. Behind him in the high shot, you can see Lex's desk with a computer monitor close to the center in front of the chair. It then cuts to an angle in front of Superman and pans across the same desk, and suddenly the computer monitor is twice the size and right on the edge of the desk, a second monitor appears on the far right of the desk, and the armrests on Lex's main chair vanish. (00:40:40)
Continuity mistake: In the overhead shot of Superman standing in Lex's office, he is standing on a stage like area raised with small stairs. The circle he is standing on is a gold color with some blue towards the outside then a gold ring. And Superman is standing almost dead center. A couple of shots later, without him moving, it shows Superman's feet and now he is standing closer to the edge, and the circle is now totally blue except for the gold ring around it. (00:40:45)
Chosen answer: When they call Doomsday a machine, they don't mean a literal machine. Just that he was built/designed. The comics were much the same. Doomsday was created by placing a baby on the most dangerous planet in the universe, and cloning that baby every time it died, forcing it to adapt. Doomsday eventually escaped this torture.
