Continuity mistake: When Peter is on the rooftop, just before he does his "I'm back" line, he begins to run. He runs quite some distance before it goes to slow motion, yet a few shots later during the slow motion, he is back to where he started running. (01:22:05)
Continuity mistake: When we see MJ and her fiancee in her room close to the end, MJ says to him "Lean your head back for me." Her hand is not in his hand in one shot, but is in another. (01:23:40)
Continuity mistake: Just after the car goes through the cafe window and almost hits MJ and Peter, they both get up and most of MJ's hair is blown back over her shoulders. However, in the following shots, there is now a lot more at the front of her shoulders, than in previous shots. Throughout the movie, her hair changes position in consecutive shots. (01:27:15)
Continuity mistake: Near the end of the film when Peter takes his costume back from inside the Bugle, Peter's boss at the Bugle takes down the note left in a web, in one shot his fingers are half way up the note, in the following shot there right on the edge. (01:29:50)
Continuity mistake: When Spider-Man takes back his suit from Jameson's office, Jameson looks up at the skyline, and there are no steel or metal bars running over the skyline, yet when the camera zooms out with Jameson yelling "I want Spider-Man", metal bars have appeared over the skyline that were not there in the previous shot. (01:29:55)
Continuity mistake: Spiderman and Octopus fall on the train carriage's roof and dent it, then roll several carriages back. When the angle changes to an outside view, they are on the third carriage and neither it nor the first two are dented. (01:30:55)
Continuity mistake: When Doc Ock attacks Peter in a cafe with MJ, he throws Peter at the wall. When Peter stands up of the wall and walks outside you can see everyone panicking and screaming. In the shot when Peter takes off his glasses and the glasses hit the floor, you can see in the background that everything is quiet and no-one is panicking, as if nothing happened. (01:32:50)
Continuity mistake: When Spider-Man is on the train with Doc Ock, Spider-Man saves two people and in this shot we see a station, yet in the following shot with Doc Ock there is no station visible in the background. (01:33:00)
Continuity mistake: When Spider-Man is at the front of the train trying to stop it, the windows at the front are already smashed, yet when he spins a load of webs, the two panes at the front smash again. (01:34:35)
Continuity mistake: When Spidey faints after stopping the train he is carried away by the passengers. One of them raises her right arm to help. A shot later her arm is lowered, and she is raising it again. (01:36:00)
Other mistake: At the end, when Peter saves Mary Jane from the collapsing structure, he jumps up in the air and swings her to safety. However if you look at the web he is holding onto it is hanging down vertically. What did he attach the web to that was directly above him, the sky? Every bit of the structure around him was/had collapsed and the only thing remotely close to swing from was the cranes. Yet we see that was quite a distance away, so Peter would have had to shoot the web away from himself not above him. (01:47:50)
Revealing mistake: In the scene right after Peter and MJ swing off and they are on the web, Peter is crawling toward MJ. You can see on his right thigh that where there is a tear mark that his skin isn't showing through, but instead there is a piece of flesh toned material. (It bends unlike the skin on the thigh would)This was probably done so the Spidey suit would still remain tight to Peter's body. (01:53:00)
Plot hole: Harry tells Doc Ock that in order to find Spider-Man he must find Peter first. Doc Ock finds Peter with Mary Jane in the cafe and throws a car through the window straight at them, then later throws Peter against a brick wall. Any normal person would've been killed instantly (or very badly injured), and Doc Ock doesn't yet know that Peter is Spider-Man. Given that Peter is his only lead on Spider-Man, it makes no sense that Doc Ock would try to kill him.
Suggested correction: Doc Ock is being controlled by the arms. They aren't behaving rationally.
Creating a series of silly explanations for obvious plot holes never resolves them. These arms were not behaving irrationally. In many scenes they were shown to be very intelligent. A good example is the scene where they attack doctors who try to remove them from Doc Ock's body. Saying that they weren't behaving rationally is absurd.
He may not have been trying to kill Peter, he could've been trying to make more of a scene of his entry, so Peter would take him more seriously and tell him where Spider-Man was. He could've been thinking of it as a risk of killing Peter though, but his arms made him go crazy.
This is only a theory. Theories never resolve mistakes.
It's not a theory. When Otto is first giving his demonstration to everybody at his apartment, a woman asks if the advanced AI for the tentacles would make him susceptible to being controlled. Otto says that yes it would so he shows everybody the inhibitor chip that he designed so he would not fall under its control. After the inhibitor chip gets destroyed, it's seen that the tentacles have not only taken control of his mind by forcing him to commit crimes, but have slowly driven him insane.
This scene is much too confusing for many people. This entry is correct. This is a mistake.
If these tentacles wanted him to finish the experiment then they wouldn't make him kill the person who has valuable information for him.
The arms are influencing his thoughts but not controlling every part of him. Doc Ock still seems to have control when defending himself but they seem to work in tandem with Ock. The only time they work on their own is when he under anesthetic. As we don't see him before he throws the car, we can only speculate the arms were trying to hurt Peter by themselves.
It's a cool scene regardless man.
Killing Peter would probably send a message to Spider-Man as well, so Ock probably wasn't concerned about being gentle.
Continuity mistake: During the train scene, Spider-Man's mask had gone partially black. We also see it when Spidey puts his mask back on. Yet when Doc brings him to Harry, we don't even see a patch of darkness on his mask.
Factual error: Considering the brightness of the fusion process, Dr. Octavius has to wear special goggles to be able to see it. Yet no one else in the room is wearing such goggles or seem hurt by watching the whole process, just as at the end of the movie. When welding something, no one can look at the arc that's created, as it would hurt his eyes and burn his retina; presumably, the fusion process would be brighter and more powerful than that, and so should have some kind of damaging effect on everyone's eyesight (except Spider Man's, maybe).
Visible crew/equipment: On the way to the theater Peter intercepts a police officer chasing a couple of criminals. At the end of that scene one of the police cars has a tremendous wreck that swings the car sideways. There is a clear shot of the driver with a black helmet on.
Continuity mistake: After Spider-Man recovers from the train incident, Doc Ock smashes in the other end of the train and throws the door on the floor in front of him. The camera cuts to another shot, and when it returns the door is no longer on the floor, nor is it there for any subsequent shot.
Continuity mistake: When Peter misses the class at the university, the way he holds his books/folders changes when the teacher talks to him.
Continuity mistake: When Aunt May hugs Peter near her "hero" speech, she hugs him with her head to his left shoulder. The shot changes and you see that she is now on Peter's right shoulder. The shot changes back and you see her on his left shoulder again.
Factual error: Dr. Octavius says his fusion relies on tritium and that there is only 25 pounds of the substance in the world. In reality, tritium is a good deal more common than that. From this article (http://www.epa.gov/radiation/radionuclides/tritium.htm): "It is used in various self-luminescent devices, such as exit signs in buildings, aircraft dials, gauges, luminous paints, and wristwatches. Tritium is also used in life science research, and in studies investigating the safety of potential new drugs." There's also a large region of water near Antarctica which is rich in tritium.
Suggested correction: According to the link provided, as well as Wikipedia (and its resources), Tritium is actually quite rare on Earth, and uncommon in natural sources.
The link provided said that tritium "is produced naturally in the upper atmosphere when cosmic rays strike atmospheric gases. Tritium can also be produced by man during nuclear weapon explosions, in reactors intended to produce tritium for nuclear weapons, and by reactors producing electricity." https://trainex.org/web_courses/tritium/reference_pages/tritium%20EPA.pdf.
