Continuity mistake: When Superman is walking through the mazelike area in Lex Corp looking for Lex, he walks down a hall that has multiple tiles and stuff on the floor. It cuts to a different angle as he reaches the end of it and suddenly the hall is much more narrow, and the tiles become singular and bigger. (00:40:55)
Continuity mistake: As Superman is walking up to the room that Lex is leading him to, it opens up and there is the red and green panel of the door on the side, but on the metal of the door frame. It then cuts to a closer, higher angle and suddenly the panel is beside the door frame on the wall. (00:41:10)
Continuity mistake: When Superman enters the ‘Rumpus Room', the red solar lamps turn on and there are lots of red hexagons on the ceiling and floor that glow as well. Throughout the entire scene, the red hexagons are never consistent in size and position from one shot to the next. It is most noticeable when Superman hits the ground after Lex's assault and the hexagons are roughly the size of his ear. But then in the high shot, they are bigger than his whole head. (00:41:15 - 00:42:20)
Continuity mistake: As Superman walks into the ‘Rumpus Room', the door shuts behind him as he crosses the threshold. It cuts to a shot behind Superman and instantly he is almost totally on the other side of the room, away from the door. (00:41:15)
Continuity mistake: Lex holds up his Kryptonite gloves and is about to beat up Superman in the ‘Rumpus Room'. When he holds up his right hand it cuts to a close up and one of the joints on his thumb piece disappears, making it a 2 piece part where it was 3 pieces. (00:41:30)
Continuity mistake: Lex says "Red and green, the colors of Christmas." When he does, he holds out his arms to his sides palm up and looks wondrously up at the red solar lamps. It then cuts to a closer angle and instantly his right arm and hand are in a different position and his body is turned differently just before he begins pounding on Superman. (00:41:35)
Continuity mistake: Lex has Kryptonite jewels on the knuckles of the metal gloves he wears when he is beating up Superman in the ‘Rumpus Room'. After he knocks Superman down and is climbing on top of him, the Kryptonite has vanished, but as soon as he stops moving, they reappear in the same shot. (00:41:55)
Continuity mistake: After beating up the clone of Superman in the Rumpus Room, Lex walks up to the container holding the real Superman's body and talks to it. There is a towel draped over Lex's left shoulder, and the shadows are on the right side of Lex's face and body. It then cuts to an angle showing Lex's reflection in the glass of Superman's container, and suddenly the shadows on his body move to the same side as the towel. It cuts to a different angle and the shadows go back to his right side. (00:42:50)
Revealing mistake: As Lex is walking away from the container that holds Superman's body, the glass of the container is reflected in the floor, as is Superman's body. But the little pedestal that he is hovering above is not reflected. (00:43:30)
Continuity mistake: Lois is caught in a daze staring at the co-worker that is now in Clark's place. She has her left arm up resting on the back of her chair. Her phone rings and she turns to look at it, and then the camera cuts to a different angle, and suddenly her arm is down off the chair. (00:43:45)
Continuity mistake: When Lois is on the phone with Martha Kent, the guy she was awkwardly staring at moments before is seen in his cubicle where Clark once was. A paper suddenly appears pinned on the wall next to his painting. (00:43:55)
Continuity mistake: There are some papers pinned to the wall of Lois cubicle as she is awkwardly staring at the new co-worker that is in Clark's spot. A bit later when she answers the phone to Martha Kent, the papers have moved closer to the edge of the cubicle wall. (00:43:55)
Continuity mistake: After Lois gets off the phone with Martha, the scene changes to just outside the Nite Club. A car pulls up and two girls get out, a blond and a redhead. When they get out in the high shot, the blond is on the right and the redhead on the left. Then it cuts to a frontal close up of the girls and they switch positions. (00:44:15)
Continuity mistake: When the girls get out of the car in front of the Nite Club, there are photographers roped off from the sides of the entrance. There are only 3 poles holding up the rope on either side of the entrance parallel to the walk way. But in the close up as the girls are walking to the door, they pass 4 poles. (00:44:20)
Continuity mistake: After getting out of the car, two girls walk up to the Nite Club past some photographers. As they do, it cuts to a close up of the photographers, and suddenly the blond guy with the backwards black ball cap has his camera lowered instantly, and the guy in the gray suit beside him suddenly turns into Jimmy. (00:44:20)
Continuity mistake: When Lois confronts Jimmy outside the night club, Jimmy turns around and has his left hand cupping the underside of the lens on his camera. When the camera angle changes, his hand is suddenly gripping the side of the camera. (00:44:25)
Continuity mistake: Once Jimmy sees Lois outside the Nite Club, he comments on what she is wearing. In the first shot, he has the strap of his camera around his neck and down his chest. It cuts to a close up as he makes his remark and suddenly the strap is gone. Then in the next shot after Lois grabs him by his earring, the strap is back, but only over one shoulder. Also in the shot where the strap vanishes, the people around him instantly change around. (00:44:30)
Continuity mistake: As Lois is dragging Jimmy away from the Nite Club by his ear, he raises his right arm for a moment. It cuts to an aerial view of this and suddenly his arm is down. (00:44:35)
Continuity mistake: As Lois is dragging Jimmy, by his ear ring, into the ally beside the Nite Club, it cuts to a different view from inside the ally. And suddenly a street light pole appears next to the building, the side walk is much thinner, the ledge outside the window on the red building vanishes, and the lighting on the side walk changes. As well as an additional row of panes appear on the yellow window. (00:44:40)
Continuity mistake: When Jimmy and Lois stop in the ally beside the Nite Club, Jimmy is in front of the window of the next building, close to the right edge of the window, and seen by the position of his feet next to the line on the side walk. It then cuts to a close up of him as he shows off his Italian silk, and suddenly he is off to the left of the window. (00:44:45)
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.
