Continuity mistake: As Perry White is telling Lois to go visit with friends or family to ease the passing of Superman, there is paperwork pinned to the wall of her cubicle behind her. It cuts to a close up of her face, and suddenly the paperwork at least doubles. (00:30:45)
Continuity mistake: In the scene where Lex kills Tess, several shots of his desk, most prominently the silhouette of him shooting Tess through the window, show that he does not have any computer towers under the desk. Yet later when Dark Superman is walking into Lex's office and he confronts him about being out of character, there are now towers under the desk. (00:34:35 - 00:51:45)
Continuity mistake: Just before we see the TV broadcast of crime levels going up in Metropolis, we see a traffic light next to the electronics shop window. On it are Don't Walk signs, a One Way sign, and the street sign. Then as the camera pulls back when the thugs start stealing the TVs, the signs have vanished. (00:32:40)
Continuity mistake: The school bus on the building has caused some damage, right under the front wheel. Moments later when Toyman appears and the goes to the top of the bus in his spider mech, there's less damage under the wheel. Also the front wheel goes from looking like a 5 point star to a 7 point star. (00:35:40)
Continuity mistake: At the beginning of the movie, Lois and Perry are arguing in his office, and you see his door. The handle of the door is on the right side. But 30 minutes later in the film when they are talking there again, the door handle has switched to the other side. It's most noticeable when Perry says "easy to lose sight of I guess in a world without Superman." And then takes a drink. (00:03:20 - 00:33:35)
Continuity mistake: As the camera is zooming in on the electronics shop, you can see the doorway and a welcome mat out front of it. But when the thugs break the window and start stealing TVs out of it, the doorway is barely visible, but the bottom half of it is now wall that connects the other sides, and the welcome mat has been cut down to a small little thing barely what it was. It then goes back to normal in the overhead shot. Also the building to the right of the electronics shop changes up in the overhead shot. (00:32:45)
Continuity mistake: Towards the beginning of the film, you see Clark pick up and then set down a picture of his mother down by his computer towers. Then 30 minutes into the film you see Lois look across over at that same picture after Superman's death and the computer towers change in design. (00:04:30 - 00:30:45)
Continuity mistake: Lois is reading a newspaper in her cubicle about the death of Superman, and there is a pencil on her desk on top of some papers. A few shots later when Perry White gets closer to her to tell her that Kent is probably fine, the pencil turns around facing a different direction, and the papers it is on move also. A stapler also suddenly appears next to her computer, and the brown book on the far end of her desk moves closer to her and turns around so the spine is facing the wall to Lois right and the pages facing her computer when it was the spine facing her computer first. (00:30:35)
Continuity mistake: At the start of the scene showing Superman's funeral, there is a yellow guard rail around the memorial stand with his coffin in front of the podium. Standing in front of the yellow rail are 13 police officers in full uniform, 7 on one side and 6 on the other. The shot cuts to the audience for a moment, and then shows the podium and memorial again from a distance shot, and suddenly all the police standing by the coffin have vanished. (00:28:10)
Revealing mistake: Doomsday drops Superman once he hears a little girl crying and walks up to her to try and smash her. As he is walking up, it shows a close up of the crying girl and she is wearing a pink shirt with denim overalls on. But look closely and you can see a mistake in how she was drawn. The straps of the overalls are incomplete and stop a few centimeters away from the buttons on them that are supposed to hold the straps in place, and the buttons are between the straps and her overalls, with a gap between the buttons and the front part as well. It's not connected at all and should be falling off her. (00:25:15)
Continuity mistake: After Superman blasts Doomsday away from him in the Subway station, Doomsday grabs him by the leg and flings him to the other side of the tunnel, breaking a large hole in the wall. As he hits, you can see there is a subway exit on the same wall about a yard or so away from where Superman hits. But then when Doomsday leaps at him to continue his attack, the wall is suddenly solid where the exit once was. (00:22:50)
Continuity mistake: Doomsday leaps into the air and smashes Superman down into the ground, crashing down into a subway station. As they are hitting the floor, you can see the brown columns holding up the roof are almost to the edge of the walkway by the tracks and touches where the tan area of the floor changes to a light green color at the end. But then Superman shoots Doomsday back with his laser vision and Doomsday looks at him angrily, and now the columns have a good few feet between them and the edge of the walk way. (00:22:40)
Continuity mistake: When Superman throws Doomsday through a building, Lex Luthor is shown watching from his office from an over the shoulder view from his perspective. It then cuts to an angle from further behind him and suddenly an antenna appears on the building, and the design of the windows change. (00:22:10)
Continuity mistake: After Superman recovers from getting elbowed in the face, he knees Doomsday in the chin and then flips over him and throws him hard at a building. But if you watch closely, the building it shows him being thrown at is different than when it cuts to the next shot to the building he hits and goes through. In fact it the building he hits looks more like the building off to the left of the one that he was thrown at. (00:22:05)
Continuity mistake: After Superman saves Lois and Jimmy in the chopper, he and Doomsday get into a fist fight for a moment, Superman getting a few good hits off, followed up by Doomsday spinning and slamming Superman in the face with his elbow. The shot cuts to a different angle as Superman staggers away and falls, and suddenly the number of spikes on Doomsday's shoulder goes from 4 to 1. (00:22:00)
Continuity mistake: When Superman sets down the chopper, there is a building behind them with some people standing around. It cuts to a very brief shot of inside the chopper as Lois removes her seat belt and then cuts back to outside the chopper, and suddenly the people standing around have moved. Also the air intake on top of the chopper changes shape and goes from a lighter blue to darker blue. The damage to the windshield becomes more extensive between shots, the glass part on the bottom of the front of the chopper goes from being two parts to one solid part, and the broken landing leg changes from a light blue to being white like the body of the chopper. (00:21:25)
Continuity mistake: When Superman goes to set down the chopper that Jimmy and Lois are in after Doomsday trashes it, the air intake vent on the top of it is smaller than seen before. Then when he sets the chopper down and lets Jimmy and Lois out, the design of the intake vent changes completely. (00:20:45 - 00:21:20)
Continuity mistake: After seeing Jimmy and Lois in their helicopter, Doomsday leaps through the air and grabs it. The window of the chopper cracks and the frame where he grabs it bends with his grip and his weight. But then as Superman grabs Doomsday, a shot from the outside of the chopper shows the window and frame fully intact, no damage. (00:20:40)
Continuity mistake: When Lois spots Doomsday and Superman from the helicopter, Jimmy is beside her holding his mouth trying to not throw up. His camera is around his neck and you can see the button to snap pictures is on the right side of the camera at the top. But them moments later when it cuts back to them, Jimmy is holding his camera to snap pictures and suddenly the button has vanished off the right side, and his finger is on the left side as if he is pushing the button there. (00:19:50)
Continuity mistake: From the air, Lois spots Superman and Doomsday fighting below, and points. It then cuts to Superman and Doomsday battling by some rubble. Cuts to a close up and then back again as Doomsday smashes Superman into the ground, and now the pile of rubble behind them has changed. (00:19:55)
Answer: It was his way of coping with grief after Superman dies. Jimmy felt he needed to be in a new environment, away from painful memories. Similarly, Perry White turned to alcohol for solace, while Lois Lane sought out Clark's mother, Martha Kent for help.
