During the science trip where Peter is bitten, Harry says that the microscope is the "largest electron microscope on the eastern seaboard". However, the microscope images shown are taken from a phase contrast microscope not an electron microscope. (Phase contrast gives less magnification but lets you work with live material, for example, the cell being manipulated in the image shown on the film).
When the name "Green Goblin" is first suggested, Mr. Jameson says something like "Call the Patent Office, I want to copyright that name." This confuses two different departments. The PTO (Patent and Trademark Office) deals only in Patents and Trademarks, while copyrights are issued by the Copyright Office. He should have said either "Call the Patent Office, I want to trademark that name," or "Call the Copyright Office, I want to copyright that name."
When Peter is fighting the carjacker in the warehouse, the thief drops his pistol to throw a knife at Peter, but when Peter thows him against the wall, the pistol is suddenly back in the car jacker's hand.
During the World Unity Festival, when the Green Goblin throws his pumpkin bomb at the balcony full of board members, as the windows blow up, Harry can be seen running away from Mary Jane and toward the area he will later have his head hit.

The morning after the field trip, as Peter is following Mary Jane, we see the car that is going to pick her up drive past Peter. When we switch to Peter's point of view, the car is nowhere to be seen. Then we go back to Peter, the bus drives up, and the car suddenly appears.

The scene at Columbia University was filmed on an unseasonably warm spring day, however, the costume department had provided the high school extras with cold-weather clothing. The real Columbia University students can be seen in the background wearing shorts and t-shirts by contrast.
When Spider-Man saves the baby from the burning building, it's amazing that the baby and the blanket are so clean - no soot, smoke damage, charring, etc. The firefighters have obvious soot around their noses from trying to breathe in that area. Did Spidey manage to give the baby a bath before presenting it to momma?
When Peter is talking with Mary Jane outside the diner where she works, watch the positioning of the shadows in the background. As the camera shoots from Peter's point-of-view, the sun is casting shadows up the street. When the shots change to MJ's point-of-view, the shadows are pointing down the street, as if the sun had just moved ahead several hours.
When Spider-Man is chasing the crook with the gun, the crook shoots 7 times through the roof of the car. Shortly afterwards you can see 9 bullet holes in an overhead shot. As the scene moves along there is another overhead shot (just after Spider-Man jumps the bridge) - no bullet holes. Seconds later the bullet holes return.

After he is disarmed of the knife, Peter kicks him up against the wall. At this point the killer has the gun back in his hand.
When Peter and Mary Jane are talking outside the diner, her trechcoat collar is first lying flat, then is tucked in, then is flat. It happens several times when the shot goes back and forth from Peter to Mary Jane.

When Peter Parker is chasing the school bus for the first time, the bus stops and it is entirely visible that there is nothing in front of the bus. When the camera is switched to the inside of the bus to show Peter stepping inside to apologize to the bus-driver, however, a tractor-trailer suddenly appears only yards from the front of the bus (visible through the windshield). Some road markings also appear.
When talks to Mary Jane on the cell phone, it's already been mentioned that cell phones don't have dial tones, but additionally, if we couldn't hear Mary Jane actually talking, it wouldn't make sense to hear her hang up either.
After Peter punches Flash in the guts during the Flash/Peter hallway fight scene, in Mary Jane's closeup she looks surprised, and behind her on her right is a surprised guy wearing glasses. After Flash's friend says "Jesus Parker, you are a freak," and Harry says "Wow, that was amazing", the same guy suddenly appears on Mary Jane's left, looking happy and clapping. It cuts to a closeup of Mary Jane and the same guy appears back on Mary Jane's right, looking somewhat surprised again.
At the end when Spider-Man dumps the brick wall on the Green Goblin, the wall is still in one piece after it's landed in the long shot, but when the angle changes, the wall's almost destroyed, and the Goblin pushes his hand up through rubble.
During the bridge scene the wire supporting the tram/cable car was obviously anchored on the other end when the Green Goblin was holding it, because the car's suspended on a near horizontal line, with the regular support at one end and the Goblin on the other. All well and good, and even after Spider-Man grabs Mary Jane we see the car drop with the wire still looped through the pulley, both ends visible. In the next shot from above though, the other end of the wire's disappeared, and the car's now just hanging off a single cable which is attached to the top of the car. How'd that happen?
When Spider-Man catches Mary Jane as she falls off the balcony, in the shot from above there are two columns lying on the ground - one on the right as we look at it, a few feet from the red area and parallel to it, and one on the left at an angle. In the shot of them landing, the one closest to the red area has disappeared.
At the World Unity Festival, Peter is taking pictures. When he looks up at Harry and M.J. on the balcony, his camera, which has been your average "right handed" camera throughout the film, magically becomes a "left handed" camera. The shot's obviously been reversed - his parting's on the wrong side as well.
When Peter Parker is walking behind Mary Jane, just after they both leave for school, and Mary Jane's father is yelling at her on the street, you see the yellow bus approaching behind them, with no car in front of the bus.

At the end of the film when Spider-Man is beating up the Green Goblin against a wall, Green Goblin reveals himself, and suddenly the distance from Spider-Man has changed from being really close as in face to face, to about 2 foot away.
When Peter runs into Mary Jane leaving her job at the diner, when she says "some dream, huh?" she wraps her jacket around her and folds her arms. After a brief cut of Peter her jacket's open - she then says "don't tell Harry", wraps her jacket around herself and folds her arms again.
In the scene on the street, right after the crook escapes with the wrestling money, Peter is standing watching all the people rush to his uncle Ben - there is a girl wearing a black leather jacket, white shirt and black go-go boots walking with 2 guys. When Peter runs to his uncle, she is behind him. When Peter pushes through the crowd, the girl is already there, to the right of the shot.
In the opening scene, we see the bus driving on the right side of the road. When the shot goes to the guy eating the doughnut, look outside the window and the bus is about 2 feet (if that) from the curb. Yet, when we see Peter in the rear view mirror, there are now a lot of cars parked at the curb that we didn't see in the previous shot.
When Osbourne is talking to Peter at the graduation, the scene keeps changing from him having one hand on Peter's shoulder to both to none. You see this just after Harry sees Mary Jane break up with Flash.

In the final cemetery sequence, Peter and Mary Jane square off for a little heart to heart, with her touching his face tenderly with her black leather gloves. The camera intercuts between front views of both: in hers, her fingers are touching his ear lobe, in his, they are a inch below his ear lobe. In one quick cut of hers, the hand has disappeared completely, then in mid-sentence as they cut back to Peter, it's there again.
When Peter is taking out the trash, and begins talking to Mary Jane, as she walks toward him you can see her underwear sticking out above her pants. As the shots change, this underwear seems to appear and disappear.
During the World Unity Festival, the Green Goblin seeks revenge upon his ex-coworkers. The Goblin throws a pumpkin bomb at them that makes them all disintegrate and disappear. One of his coworkers had a wheelchair with him, which survives the Goblin's bomb and remains on the balcony. (You can see the wheelchair while they are being bombed and after they disintegrate, all in the same shot.) For the rest of the scene, the wheelchair has disappeared from the balcony.

When Peter is trying to talk to Mary in the cafeteria you can see behind where he is standing there are numerous people and tables between him and the back wall. Peter then sits down and in the very next shot his table is one table away from the wall behind him. The shot may be lower but is from the same angle as before.
When Mary Jane and Peter are talking in the street right after she left the diner, every time a car passes by behind her and then the camera goes to Peter, those cars would mysteriously vanish since you can clearly see that there are no moving vehicles behind him.
In Jameson's office you can see a building across the street through the window, but when Spider-Man is gassed and falls out, a shot from the street shows Spider-Man falling from an extremely high building that has no other buildings near it.
In the scene where the building is on fire, you see a fireman (helmet has 57 on it) assisting in getting the residents out of the structure. Take notice that the fireman has an annoying strap hanging down from the top of his helmet. Eventually that strap disappears and a convenient microphone comes into focus. Stick around, because the microphone has a vanishing.

After beating up the thugs, Spider-Man leaves through some dark alley way and Mary Jane looks around to find him. Suddenly, Spider-Man comes down his web, upside down, along a wall. She's about 3 feet away when he starts speaking, but when the angle changes and she jumps around she's right in front of him.
At the end of the film just before Norman Osborn's glider zooms in and kills Norman, Norman is standing right by the hole in the wall, yet when the glider hits him, he has moved quite some distance to his left and is now at a large part of the wall.
When Peter is following MJ up the street, there are two cars and a jeep in the background. When Flash picks up MJ and speeds away, Peter runs from in front of the jeep, which was further down the street. Also there is now only one car in front of the jeep, instead of several.
When Osbourne is on the table with the wires attached to his chest they go from both pointing to about 2 o'clock, to both nearly being vertical, to being one vertical, one angled, then just before he bursts out, the one of the left's pointing down.

When Peter has just seen MJ leave her house for school and is walking along the pavement by the cars following her, he stops when she does and practises talking to her. Look behind him. You can see the bus turning the corner and coming nearer to them. The shot stays on Peter when the bus rounds the corner, cuts to Mary Jane and then goes back to Peter. The bus would have been much nearer than it was in the second shot at the speed it's going.
Near the end of the film the Green Goblin programs his glider to fly at Spider-Man, Spidey jumps out of the way and the glider continues to fly at the Green Goblin.

Then in the next shot from further away his hands are back by his head.

When we see Norman Osborn testing out the formula with the other doctor, Norman comes back to life and grabs the other doctor, in the first shot from the front when he grabs him, his fingers and knuckles are straight against the doctors neck, yet from the back we see now its more of a fist.
In the film Norman Osborn is talking to the board of the company where they announce they are selling the company. In one shot if you look on the table most of the folders that the board are holding are open. In the following shot most of them are closed.

In the middle of the film when we see Peter, Harry and Norman Osborn talking, Norman says "Perhaps you could tell me who she is, this mystery girl Harry's been dating" If you watch Harry, in one shot he has both arms on the table and in the following shot, he is one arm up and is scratching his head.
At the Unity Festival, when the Green Goblin flies past on the glider, the camera cuts to a shot of the balcony, and behind Harry and MJ there is a man in a black suit that takes a picture (you can see the flash from the camera). But when the camera cuts to a close up, the camera that was in his right hand has vanished and is now a glass of wine.
When Norman Osborn finds out he is the green goblin from his mirror reflection, watch closely at his hair in the reflection and the real him, his hair in his reflection has a thick strand of hair hanging over his fringe, and the actual him, has his hair without any parts hanging over his fringe. It changes about three quarters of the way through the scene.
Close to the end of the film when the Green Goblin bursts in the window of Aunt May's house, in one shot you can see she is leaning by the side of the bed, and in all other shots she has her head on the bed.
In the big carnival scene when the Green Goblin has thrown a bomb at the balcony the shot cuts to Peter and he sees two people about to get crushed by a falling rock.

The shot changes and they have there backs to Peter and the woman is now on the left, the man on the right.
When Norman Osbourne is in the tank, there is a close up on him at one point, and he has an expression of despair and fear on his face. But in the next shot, a wide one showing the green gas filling the chamber, Norman has a completely different look on his face.
When fighting the Carjacker, Peter dropkicks him using a pipe. When Peter does this, the Carjacker has his cap on as he moves out of frame. When moving into the next shot, the Carjacker no longer has his hat, which now disappeared into thin air, never to be seen again.
In the Thanksgiving scene where they are waiting for Peter to arrive, Peter swings onto the side of the building and drops down onto the balcony of his bedroom.

When he unbends them and takes off his mask (the next shot) he is in the center of his bedroom, not on the balcony where he landed in the shot previous.
When Peter is talking to Mary Jane in front of the diner, a light maroon colored caddy passes by twice. The first time when she says she just got off a job, the second when the boss shouts at her. Sure, there could be two cars the same color in NY, but with the same driver...?
When Peter catches up with Mary Jane outside the cafe, there is a motorcycle that passes by Mary Jane. When the camera cuts back to Peter there is no evidence of a motorcycle passing, not even a sound.

In the scene in Jameson's office after he throws his cigar out the window and the Goblin throws it back, when Jameson is looking at the cigar on his desk, he is sitting at an angle. Right before the Goblin crashes in, Jameson is sitting perfectly straight at the desk, with both hands on the desktop.
When Spider-Man finishes beating up the thugs and after Mary Jane kisses Spider-Man, when you watch the one shot from the side, Mary Jane only starts to put his mask back on. But when the angle changes, Spider-Man's mask is properly on when Mary Jane didn't even move her hands.
In the Thanksgiving dinner scene, watch Mary Jane's arms after Norman asks Peter to repeat how he got hurt. When she is shown close up, her arms are folded. In the long shot, her hands are in her lap. They jump back and forth between the two positions.
When MJ and Peter are discussing the beating that Peter gave Flash that morning in school, MJ says, "He's just glad you didn't give him a black eye for graduation." This scene takes place the day after Peter was bitten by the spider, when the weather is cold. High school graduations generally take place in June or late May - so any black eye Peter might have given Flash would long be healed up by graduation.
In the scene where Osbourne tries the performance enhancers on himself, he takes off his labcoat and throws it into a corner. We see a long shot of the lab, and the coat is in at the base of the pillar. In a subsequent long shot however, the coat has moved a foot or so.

This time the window is all the way up. When the camera comes back to Mr. Osborn again, there is someone leaning in the window talking to the driver. The next time the camera comes back to Mr. Osborn, the window is again halfway down.
When Uncle Ben's killer enters the warehouse he reloads his gun and pulls the slide back to cock it. Later, when he points the same gun at Peter, you can hear the distinct sound of the hammer being pulled back. However, despite cocking the gun twice, you can see that the gun is not cocked.

When Peter smacks the food tray onto Flash's back, the tray hits Flash on his left side. The stain from the food is shown on this side in differing sizes except for the moment Flash stands up and turns around, saying "Parker" - in which it is shown to be a huge stain on his right side.
During the World Unity Festival, when Peter Parker sees a huge piece of stone from the building falling rapidly, the camera shows a man and woman facing the camera and cowering.

During the field trip, Harry, Peter, and Mr. Osborn are talking outside the building, the students are walking up the stairs in the background during one shot and not in the background at all in the next. Later they return in the background once again.
During the World Unity Festival, when Peter runs toward camera and unbuttons his shirt, the Spider-Man suit only extends to the top of his chest. However, when he removes his mask during the Thanksgiving sequence, the costume clearly goes all the way to his neck.
The morning after the spider bite, Peter comes downstairs and
startles his uncle. Just before he does that, Uncle Ben can be seen holding a cup with both of his hands, yet in the next shot, he is holding it with just one hand. He also pulls the cup away from his face "twice", once in each shot.
At the World Unity Festival, a block of stone falls from the balcony and is headed for a man and his wife. When they are shown flinching at the stone about to hit them, the man is on the left side of his wife. When Peter spins his web onto them to save them, he is on the right.
After the kiss, MJ tries to adjust the mask of Spider-Man, by pulling it up, of course. But when the mask reaches the end of his mouth, Spider-Man launches his web to leave and the mask is magically adjusted.

When Peter walks behind MJ on the street, the school bus turns the corner and approaches slowly in the background. Ten seconds later, when the bus is shown a third time, however, it is still passing by the same vehicle.
When Peter is first becoming aware of his "spider sense" in school as Flash is approaching from behind, he sees a fly and a paper airplane moving in very slow motion. The fly has two wings when in reality, flies have two sets of wings, the main wings plus a smaller "halter" wings underneath (to maintain balance in flight), for a total of four wings.
Before going into the vapor chamber, Norman announces to Stromm that he's drinking a vial of prochlorperazine, which will serve as a catalyst for the human performance enhancer. Prochlorperazine is better known as Compazine, a medication formerly used to control extreme nausea and vomiting--it wouldn't have helped the enhancer at all.
When Peter is walking behind Mary Jane, on the way to the bus, he stops and talks to himself. over his left shoulder is a car parked, with a Massachusetts license plate. Cars from many different states visit or pass through New York on a daily basis.
When Peter is practicing his web-slinging in his room and catches the lamp to pull it towards him, it doesn't appear to move very fast off the chest and looks more likely to fall on the floor before the shot changes. When it cuts to Peter, it speeds past his shoulder a lot faster to smash on the wall behind him. Furthermore, Aunt May would have easily seen the amount of webbing all over the room through the gap in the door as she's talking to him.
When Spider-man swings MJ to safety and we see them swinging close-up, not only is MJ's hair blowing in the wrong direction, but Spider-man's head, neck and shoulders appear to be stiff as if it were a mannequin she is holding on to for the sake of the shot.
When Spider-Man is chasing the carjacker, a brief shot from the inside of a police car shows they are moving at only 15mph. This is not nearly as fast as the obviously sped-up sequence leads us to believe.
Although Peter is supposed to have perfect vision after his bite, Tobey Maguire's contact lenses are visible at various points throughout the movie. It could be that Peter took to wearing "blank" contact lenses to account for the fact that he no longer needs glasses, but is more likely to be a true goof.
When MJ is in front of the spider cage, just prior to Peter being bitten, a spider on a thread can be seen just over Peter's right shoulder in the medium shots, and directly underneath the spot where he will be bitten. It disappears in the final cut before closeup coverage begins. Notice also that the focus changes on the background, indicating the use of different lenses or different spikes for the shots used.
When Flash tries to beat up Peter, a crowd of students gather around them. When Peter knocks Flash down the hallway, though, those students have created an alley for Flash to fly through. Given the superhuman speed with which Peter punched Flash, none of the students would have had time to step aside, anyway - they would simply have been bowled down.
After depositing MJ on the green lawn at the church, Spider-man obviously jumps off of a mini trampoline over the hedge. As MJ runs behind to follow, she clearly has to step around the mini trampoline to approach the hedge.
When Spider-man jumps on the car, there's an in-car shot of the carjacker firing up at the roof. When the camera goes back to Spider-man on the roof of the car, the bullet hole switch position. In fact, if the bullet holes had stayed in position, Spider-man would have been killed.

While Peter Parker is practicing the web shooters he breaks a green lamp, moments later when Aunt May opens his door to check on Peter, the green lamp can be seen on the shelf next to the door, fully repaired.
When Peter Parker first discovers he can climb up walls (while in citizen clothing), he tests it out by climbing up a building in an alley. During this scene, you can clearly see his clothes hanging out forwards, indicating that the scene was filmed with him crawling along a floor horizontally.
Flash attacks Peter in the school's hallway. We are supposed to witness Peter's incredible speed in one shot, as he dodges a punch in slow motion. Flash's bracelet, however, is motionless. The speed of the punch would throw it back and forth, as it does throughout the rest of the scene.
After rescuing Mary Jane and leaving her at the church, Spider-Man apparently uses a trampoline to jump off the ledge - he jumps up onto something before springing off. Mary Jane then runs forward and clambers around something to get close to the edge.
When the Green Goblin attacks J. Jonah Jameson at the office, Spider-Man shows up. Goblin turns his glider to face his nemesis. If you look closely, you can tell that it is a rotating rig, and that the film was sped up. Goblin's body shifts abruptly while he turns, and the fire in the background is moving too quickly to be at normal speed.
When Peter is just getting to the science lab at the beginning right after his friend gets out of his fancy car, if you look at the extras walking behind the two, you will see a BRIGHT red haired girl walking by, going towards the building, but when the camera focuses on Peter the girl is there again, walking the opposite way on the other side of the huge sidewalk. You see her about 5 times going back and forth to the building. The first few times she's alone, then she's walking with another girl.
During the final fight with the Goblin, Spider-Man is up against the wall and the Goblin goes to stab him with his "quad bladed knife". Spider-Man grabs 2 of the blades and while pushing back you can see all 4 ends of the blades vibrating up and down as if they were made out of rubber.
Peter Parker climbs his first wall in an alleyway. Look carefully at his shadow - it is directly in front of him on the wall the whole time, indicating that he is being lit from directly behind. The only thing behind him is the opposite wall. The only possible light sources would be from the opening of the alleyway (which would have cast a long shadow to his left) or from above (which would have cast a long shadow behind him).
At the end of the movie, when Peter is placing Dr. Osborn on the couch after he died, as Peter is lowering him, Dr. Osborn's hand changes from being stiff to the hand moving to help being put down. While it's possible it was a natural reflex, I don't think that they are able to help lower themselves with their own hand. Dr. Osborn had been dead for a while anyway.
When the car jacker who stole Uncle Ben's car is being chased by the police, they seem to be doing a high speed pursuit. However when the car goes over the corner and demolishes a stand, a cut shows the inside of the car. The digital speedometer is reading 15-17 mph, hardly much of a challenge for the police to catch.
When Osborn is gassed inside the vault and the doctor comes to aid him, 2 green squares are reflected on his glasses. From the opposite angle there's no green wall anywhere, so it was the green screen used on the set.
During the World Unity Fair, Times Square alternates between the real Times Square and the digitally altered one created for the movie. The main difference is that the altered version doesn't have the gigantic Cup-O-Noodle sign.
The Cup-O-Noodle sign can be clearly seen twice, and the bottom of it a 3rd time. First time when you first seen the Goblin flying in the distance, and the 2nd is during the shot from behind in when she flies past the Earth balloon before throwing the first bomb, the sign is on the left. Then when Goblin is flying off, you see the bottom of it.
The extras at Columbia University are wearing cold weather clothing, appropriate for the seasonal setting. Students in the background wearing shorts and t-shirts blow the illusion and reveal that the scene was shot on a warm day.
When Mary-Jane is attacked in the rain in the alley Peter is shown running along the roof changing into his costume, you can clearly see he is already wearing his mask, but when he fights the thugs he has no mask.
When the car-jacker walks into the deserted warehouse, he has the gun in his left hand and the money bag under his right (flipped image). Next cut is to him reloading, and the gun is back into his right hand.
It is established that Peter is right-handed, but when he is designing his Spider-Man costume, there are two quick shots of him drawing with his left hand. These shots are most likely flipped images, rather than a suggestion that he's ambidextrous.
When Spider-Man is hit by the bomb at the end in the destroyed hospital, the Green Goblin comes down and rises his eye lids on his mask, "misery, misery, misery, that's all that you've chosen," Then in the next shot where he says "I offered you friendship and you spat in my face." The eye lids are closed, but when he is about to stab Spider-Man with the trident, the eye lids are opened, and when he is pushed onto the brick wall, they are closed, they stay closed the rest of the scene.
When Spider-man's arm is cut during the fight with Green Goblin in the burning building the cut runs diagonally down his arm toward his thumb. In the Thanksgiving dinner scene when Norman Osborn sees the wound it runs diagonally down his arm toward his little finger.
When Spider-Man jumps over the oncoming bladed glider, which hits the Goblin instead, the glider seems to hit at about stomach level and pin the Goblin to the wall. But in the next shot, it is lower, seeming to have hit at groin level, to allow the Goblin to slump forward across the glider.
When Spider-Man fights the carjacker, they enter the building on the ground floor but then the carjacker trips and falls out what appears to be a 3rd story window even though neither of the two characters can be seen climbing to a higher level during any part of the fight sequence.
When Peter Parker gives chase to the killer of Uncle Ben, he wears the same outfit he wore when fighting Bonesaw. Peter climbs a building and then jumps from building to building. He winds up on a dome shaped roof and works up the nerve to web sling. The figure shooting the web from that dome is Peter in his Spider-man suit which does not invent until later in the movie.
In the bridge scene, after the Green Goblin destroys one of the stations, he flies down, grabs the wire for the cable car it and pulls it upwards with him to the top of the bridge. However, despite that he's strong enough to hold it himself, the glider he's on barely has enough thrust to carry a humans weight on it, so the chances of it being able to fly upwards whilst holding onto a wire attached to a huge cable car is unlikely.
When Peter realizes that Uncle Ben's killer is the thief he let go at the wrestling arena, his flashbacks are very inconsistent to what really happened. The gunman originally nodded his head very quickly and said thanks sounding out of breath. In Peter's flashback, the gunman stands there and smiles and says thanks as the elevator doors close. This is to show the subjective memory of a grieving Peter in contrast to the objective portrayal of the event.
When Peter Parker calls MJ on the phone and gets her answering machine, the Green Goblin answers and he taunts Peter calling him Spider-man. This is all being recorded by the answering machine, so MJ might listen to it and discover that Peter is Spider-man. But not if Goblin erased the message immediately after the call, which is what most likely happened.
Right before the Thanksgiving dinner, Spider-Man and the Goblin get in a fight in a burning building. In the outside shots of the burning building, the green leaves on the trees clearly indicate that it is summer time in New York. After the Thanksgiving dinner, Aunt May is attacked by the Goblin. In the outside shots of her home, once again all the trees are green.
In the final conflict, Spider-man tries to save both the falling children in the transportation device and Mary Jane all the children and the teachers are screaming. However, one man inside with the children who either controls the device or is a fellow teacher seems somewhat relaxed as it is falling. It is unlike that he would be so relaxed as it is falling while everyone is going crazy.
