Corrected entry: Towards the end, during the climatic fight between Spider-Man and Green Goblin, there is a part where Goblin is against a wall (this is just before he spears himself with his own hoverboard) and the floor at his feet is fairly intact, but when Peter jumps down the floor is a lot less intact (this is shown from a sideview displaying both Goblin and Spider-Man).
Corrected entry: When Spider-man first gets his new suit you can see the world trade center in his eyes when the film came out in 2002.
Corrected entry: The whole scene where Peter is testing his web powers by swinging across the road and hitting the billboard on the roof defies the laws of physics no matter how you try to explain it. Peter, the web line and the crane were a pendulum, so if the crane were behind or directly above the sign, Peter would not have lifted back up because he didn't pass under the pivot. If the crane were before the sign, he would up swing but would not have been able to slide down the sign immediately after impact because he would have swung backwards toward the pivot again meaning he'd need to wait until the back-swing reached zero and went in the other direction towards the sign; this would take several seconds.
Corrected entry: The newspaper advert Peter sees is for amateur wrestlers, yet the wrestling shown is in the squared circle of professional wrestling.
Corrected entry: When Peter's auntie enters when his uncle is looking for jobs in the paper, a boom microphone can be seen bobbing up and down at the top of the screen. (seen in the DVD, not in a movie theatre).
Corrected entry: Right before our favorite hero saves the young boy from being crushed at the World Unity Festival, notice the white string on his back. It's really pretty obvious. It's also in the shot right after Spiderman says "Come on, move kid."
Corrected entry: When Peter is learning about his new improved eye-sight, he takes off and puts on his glasses a few times. When he puts them on, the whole screen gets fuzzy, but only what you see through the lenses should be fuzzy, not the area outside the lenses too. (00:17:15)
Corrected entry: When Spiderman has his first swing around NY with his new suit on, you can see the WTC in the reflection in Spiderman's eyes. (Directly after the man in the subway is paying the Spiderman theme song on his guitar) (00:55:45)
Corrected entry: In the wrestlers' cage fight Spider-Man is on his knees, on the mat, when he shoots two webs to the roof of the fight-cage (web length = floor to roof). These he uses to jump over Bone Saw. The webs are never seen hanging in the cage again, even at the end when the cage is wide open. (00:40:30)
Corrected entry: When the students visit the lab with the genetically altered spiders, the female scientist says spiders belong to the Class Aranae. Actually, Aranae is the Family, and spiders belong to either the Class Arachnida or the Class Chelicerata, depending on which classification you use. This is a huge error - 'family' and 'class' are very specific taxonomic terms which no real geneticist would ever mix up or use interchangeably. (00:06:15)
Corrected entry: In the wrestling scene, the cage is ceremoniously locked. As soon as Peter defeats Bonesaw, the cage is raised and the sides separate. How did it get unlocked so fast?
Corrected entry: During the scene on the roof after the Green Goblin knocks Spider-Man out at the bugle, you see the Goblin talking to Spider-Man. When Spider-Man first wakes up and the camera pans to the Goblin, you see him open his yellow eye shields. Then, when the camera shows a close-up of the Goblin talking to Spider-Man, you can clearly see that his eye shields are closed. Then when the Goblin leaves Spider-Man to think about joining him, his eye shields are open and he closes them and takes off.
Corrected entry: When you first see the cable car (at the end) it says Universal Pictures. When you see the car the second time, it says Roosevelt Line.
Corrected entry: In the building fire, there are 2 windows still intact at Spider-Man's arrival. He busts out one by swinging through it, and when he leaves with the child there is an explosion which blows out the other window. Thus no windows should remain intact. But, when Spider-Man goes back into the building to rescue "the woman" (Green Goblin) he smashes through another window.
Corrected entry: When Spider-man jumps on his uncle's car chasing the dude who shot his uncle, Spidey punches through the roof. Later, when the car crashes, there's no more hole.
Corrected entry: When Peter gets out of the car when Ben gives him a lift, we see there is a bit of his costume sticking out under his shirt, but when we see him a second later, the costume can't be seen.
