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.
Corrected entry: During the Festival, when the Green Goblin throws the bomb under the balcony the windows above the balcony all break, but when Spider-man goes to save MJ the Green Goblin catches Spider-man and slams him into the the window and the glass breaks again.
Correction: The glass above never breaks when the bomb goes off - only the glass below the balcony breaks. Above the balcony the only visible damage is a few sparks from a bust light fitting.
Corrected entry: Peter Parker use a manual focus, manual wind camera throughout the film, yet in the sequence where he photographs himself as spider-man, the camera happily auto-winds and auto-focuses.
Correction: Most professional or semi-professional cameras have both - manual for the most precision, but auto for when you really need it.
Corrected entry: We all know that Peter Parker wears his Spidey suit under his clothes in case of an emergency, that way he can make a quick change. But what about the boots to his Spidey suit? He can't wear them under his shoes because they are too thick and isn't seen holding a big enough bag. So where does he keep them?
Correction: They must be thin enough - in the scene where MJ is being chased by the thugs into the alley, Peter is seen from a rooftop angle pulling off a shoe exposing his boot, worn underneath.
Corrected entry: At the beginning of the movie, when Peter is chasing after the school bus you can clearly see a bridge ahead of the bus. But neither the bus, nor Parker, go under the bridge.
Correction: The shot with the bridge is arguably just an opening shot - the chase could easily start after the bridge.
Corrected entry: During the end sequence, Spider-Man originally did his final swing through the World Trade Center towers, landing on top of the tower with a flagpole on top. This was changed after September 11th so that he lands on the Empire State Building instead. However, during the pan around him after the landing, you can still see the Empire State Building, which he just landed on, in the background!
Correction: It is the American International building, which looks similar to the Empire State Building.
Corrected entry: In the beginning, when Peter runs out to catch the bus, he swings his backpack over his shoulder, but when he is seen running after the bus, the backpack has disappeared.
Correction: It's there - his top covers the strap from the front, but you can see it in the side shots.
Corrected entry: When Peter enters the wrestling arena and we see Bonesaw fly off the corner of the ring, the guy on the floor has his arm across his body/stomach. Yet, when Bonesaw flies through the air, you can see the guy on the floor move his arm ready for him to land on top of him. (00:35:20)
Correction: Where's the mistake? Wrestlers actually do that.
Corrected entry: Peter Parker practices web shooting for the first time in his bedroom. When Aunt May checks on him the webs criss-cross the room from wall to wall. Think about it... he's shooting the webs from his wrist. What we should have seen was several strings hanging from the walls. To get the room as we see it, every time he shot a string he would have to walk to the other side of the room and attach his end to the opposite wall. Not likely. (00:32:20)
Correction: He shot it to the first wall then kept the stream going until it hit the second wall without breaking the link, just aiming it at a different part of the room and then back and forth without stopping.
Correction: On the factoids track of the DVD it says that his red sweater poking out was an intentional "superhero faux pas". Most likely to convey that he is still learning the rules of being a hero.
