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. [Peter's weblines have considerable elasticity to them, giving the whole setup some decidedly un-pendulum-like properties. As such, the pendulum model cannot really be considered suitable for analysing this scene for possible errors.] Corrected by Tailkinker

The newspaper advert Peter sees is for amateur wrestlers, yet the wrestling shown is in the squared circle of professional wrestling. [The event shown is a pro wrestling event - the ad is part of a PR campaign where amateurs get to challenge professionals in between scheduled pro matches.] Corrected by Twotall

It may just be me but, when Peter suddenly stops wearing his glasses shouldn't his aunt and uncle have noticed? Mary Jane notices at school yet the people that have raised him never say anything. [Maybe they said something to Peter when the camera wasn't rolling. Peter is never shown using the bathroom, but I have to assume he did. He is never shown doing laundry, bathing, and many more routine and needed things. Do you really want to see any of that in a film?] Corrected by Rlvlk

In the museum, Peter and his friends are shown real-time videos of live, moving biological specimens shot through 'the largest electron microscope on the Eastern seaboard'. You can't film live specimens in an electron microscope. The electron beam only works in a vacuum chamber, in which the specimen - invariably dead - is held. [The Spider-man universe isn't exactly the same as ours. Look at some of the technology displayed in this film and the sequel (a man basically builds a sun). They may have an electron microscope that can do that.] Corrected by Gary O'Reilly

In the scene near the beginning when Peter does his little trick on the stairs when he's coming down for breakfast, we see Uncle Ben drinking tea/coffee, he looks in Peter's direction, and in the following shot he is looking in his direction again. [Uncle Ben is doing a double take because Peter surprised him just as he was taking a sip of hot coffee] Corrected by Twotall

At the beginning in the museum scene, in one shot when the class moves on and Peter and MJ are left alone, Peter asks "Can I take your picture? I need one with a student in it." When he begins to take pictures, when the camera cuts to a view of MJ, she is smiling and looking in another direction, not at the camera. (If someone was taking your picture, you would be looking at the camera. MJ is not). [So? I have many times looked away from the camera when someone was taking my picture. If MJ and Peter feels that the picture is better (for instance, more natural than a stiff, posing heads-on shot), it is their choice.] Corrected by Twotall

At the World Festival, when the Green Goblin punches Spider-Man into a pole, he says, "Impressive," yet you can see his mouth through the gauze of his mask and his lips don't move. [If you turn up the brightness on your TV, you can easily see that his lips do move, albeit a little bit.]

When Peter discovers he can climb walls, there is a shot which shows hairs on the tips of his fingers. For the rest of the movie he has a costume which includes gloves. How is he supposed to climb, now that his fingers are covered with a homemade costume? [That is exactly why they came up with the idea of the micro hairs. The spandex that he wears is thin enough that the hairs poke through and grip for him.] Corrected by Garlonuss

In the shot where Spider-Man rescues Mary Jane from the balcony at the festival, one of his web strings is not hanging onto anything. [He only needs one string to hang on to in order to rescue her. If the other one missed, it's not a problem.]

Near the beginning of the movie, when Dr. Osborn is in the lab testing out the chemical thing and Dr. Stromm straps him into the chair, Dr. Osborn exclaims that the metal bars holding him into the chair are cold. In later shots, you can see that the bars aren't even touching his body. [The metal touched him when he was being locked in, before he'd properly settled into position.]

In the scene with the Green Goblin has MJ in one hand and a sky-tram in the other, he is not attached in any way to anything else. Since the Green Goblin does not have the ability to stick to objects, the weight of the sky-tram would pull him straight off the bridge. I know he has super strength but that doesn't make him impervious to the laws of physics. [Although it's not stated, the Green Goblin must have some kind of magnets in his boots, or else 1)he could never stay attached to the glider while it was moving at a quick rate of speed, and 2)when he first catches the sky-tram, it would have ripped him right off the glider. Magnetic boots, as weird as it sounds, makes sense.]

The scene in the science lab, after Norman tries the performance enhancer, he is held down on the bed with metal arms. In the next scene when the other scientist runs in to see if he's alright, the metal arms aren't holding him down anymore. [Dr. Straum probably made the computer lift them up when he saw Norman's heart failing so he could pull him out of the chamber if he couldn't successfully perform CPR.]

At the World Unity Festival, the Green Goblin throws a pumpkin bomb at some windows. It hits the wall in the middle, not going inside. If it exploded outside, the windows should have shattered and fallen into the building, but instead the windows blew outwards. [It goes into a window that's partially open and blows up from the inside.]

What exactly is the Green Goblin's plan in his last scene where he dies? By standing up, he has aligned himself between his knifed hoverboard and the brick wall, which eventually kill him, but as he controls the hoverboard and knows what is about to happen, why has he put himself in harm's way? Had it gone to plan, both he and Spiderman would be impaled. If he would have jumped it, why didn't he anyway, nothing stopped him. Whilst crazy, Goblin is a very clever character who has planned this move, so why does he stand up? [He stands up because the glider's going to come in low enough to hit him anyway - it'll be much easier to avoid if he's up on his feet. He's expecting his glider to impale Peter, which would slow it down, giving him enough time to get out of the way. Peter leaping out of the way was completely unexpected, distracting him for long enough for the glider to hit him instead.] Corrected by Tailkinker

In the scene where Bonesaw McGraw hits Spider-Man with the chair and it makes a metallic sound. In the next part Bonesaw throws the chair on the ground and it only make a soft thud even though it hit concrete. [Bonesaw is in a steel cage with a wrestling mat, the chair never hits the concrete. It would have landed softly onto the mat, not making a sound.]

The firemen don't seem to be doing anything when Spidey was saving the baby or the "screaming woman". [It would be dangerous for the firemen to be spraying while Spider-man was still in the building, or they may hurt him and the person in trouble.]

When the Goblin first appears and starts following Spider-Man, Spidey is in the floor and shoots a web to lift, but it actually looks like the web lifts him magically without him doing anything like pull it or something else. It looks like someone pulled his web from the other side. [Most spiders have the ability to reel their webs back into themselves. Naturally, we're to assume that Spiderman has this same ability, and is using it to lift himself.]

I don't understand how Spidey is able to go back up the web, when he does the cool hanging upside down thing with the criminal who stole the money. He sort of grabs the web a bit higher and he goes straight up. He can't reel web back into himself... [Many spiders are able to 'reel' their web back into themselves, and Spidey had the ability also.(See answer to question on the question segment of this page).]

In the scene where Mary Jane is attacked by the four thugs in the alley, there is an over-head shot of her fleeing with the thugs shouting 'Hey! Where you going, baby?' and as this is happening, we see Spider-Man running along the top of the nearby building taking his shoes off. If you put the screen on pause or slo-mo, you can see he definitely has his mask on (check out the reflective lines on his head), but seconds later when he is pulling the thugs off Mary Jane, he has his mask off. Why would he take his mask off when he wants to keep his identity unknown? [Spidey's mask was most likely thrown off or taken off by one of the thugs because as said, Spidey didn't want his identity known so he wouldn't have done it on purpose.]

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. [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. ]
