Continuity: In the scene when our hero, 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.

Continuity: During the scene in which Peter is introduced to Norman Osborn in front of the museum, keep an eye on the Volvo parked behind the Rolls Royce. When the camera first faces Mr. Osborn (Willem Dafoe), the Volvo in the background has the window rolled halfway down. Camera switches to Peter and Harry, then back to Mr. Osborn. 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.

Visible crew/equipment: When Peter stands up after being bitten by the spider, there's the reflection of the cameraman with headphones on the television set behind him.

Continuity: 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.

Continuity: In the scene where Norman is getting ready to test himself he lays down on the bed fastens himself in and the doctor goes to the computer. However when it shows him being brought in to the chamber he has several electrodes connected to his chest and head.

Continuity: Near the beginning of the film when we see Peter waking up and reaching for his glasses, in the previous shot he didn't have the blanket on him or over his shoulders, it's in the background on the floor, yet when he reaches for his glasses the blanket is on his shoulders.

Visible crew/equipment: In the scene where Peter wakes up and discovers he can't see through his glasses you can see a phantom hand on the left sliding out of view in the mirror. This happens the last time Peter tries to see through his glasses. It's not a reflection of his hand due to the angled edge - it's on the main part of the mirror.

Continuity: 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.

Continuity: When Peter accidentally flings the tray of food on Flash it hits him on the left shoulder but when Flash stands up the stain temporarily jumps over to his right shoulder.

Continuity: When Peter shoots his web at his bedroom lamp and pulls it across the room, it smashes against the wall and breaks. But when Aunt May is talking to Peter from the door seconds later, the lamp is back on the dresser in one piece.

Continuity: When Peter is practising throwing spider webs in his bedroom, his first attempt hits a model rocket and it breaks in many pieces. A few shots later when he finally hits the Dr. Pepper can, as he whips it across the room you can see the rocket back in one piece, just leaning against the wall.

Continuity: When Peter shoots webs around his room and hits the rocket over, all that is on the nightstand is the cool light bulb lamp, the picture and the Dr. Pepper can. When it flips back to the nightstand again you can see some weird green alarm clock next to the overturned picture.

Continuity: When Peter and his uncle are talking in the car, and the camera is on Peter, you can see lots of plants and bushes in the background. When he gets out of the car, there are no plants or bushes.

Continuity: 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.

Factual error: In the graduation scene, watch for the giant spiky orange flowers behind Norman Osborn. These are tropical birds of paradise flowers which grow all over California but would never survive in New York. [Confirmation of that: one contributor was taking a studio tour at Sony studios in Culver City, CA on March 26, 2001, and saw the filming of the graduation scene, complete with Tobey and Kirsten zipping by sitting side-by-side in the jump seat of a golf cart.]

Continuity: 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.

Revealing: In the scene after Spider-Man stops the convenient store robbers, it shows a newspaper article. This article virtually repeats itself. Here's what you can read: "Witnesses claim an unknown masked man was seen exiting the Ling Deli after stopping two suspects from attempting to rob the establishment. Police spokesman John Young said "we've heard of Samaritans, but in 20 years I've never seen anything like this." The two suspects were taken to the county jail....(cutoff)....attempting to rob that same establishment. Police spokesman John Young said "we've heard of Samaritans, but in 20 years I've never seen anything like this." The two suspects were taken to the county jail."

Other: In the scene where there are shots of newspapers with articles about Spider-Man, if you look closely at the shot of the newspaper article just before the shot of Spider-Man putting on his mask, the second column is repeated in the fourth column - easiest to spot is "NYPD spokesperson, Sean Young..." appears twice.

Continuity: When Peter is talking to Mary Jane outside the diner, the same man is seen walking behind Peter 3 or 4 times - biggish man with a flat cap on. First when Peter says "so you're acting now?", then when he talks about Harry not living on earth, then again when Mary Jane walks off.

Continuity: When Spider-Man is taking snapshots of the armored car burglary, one of the burglars says "watch the street". As the camera snaps you see them pointing rifles or machine guns towards the sky and when Spider-Man lands on them to dispatch them, the weapons are gone...
