Continuity mistake: 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. (01:06:50)
Continuity mistake: 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. (01:02:10)
Continuity mistake: 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. As the camera angle changes, you see a black convertible pull up to pick up Mary Jane, and it arrives before the bus, even though the car was nowhere to be seen a second prior. (00:19:15)
Continuity mistake: At the end of the film when we see Norman Osborn offer Peter his hand, if you watch he offers his hand twice. (01:44:20)
Continuity mistake: 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. (01:43:25)
Continuity mistake: During the fight scene at school, the food that was just on Flash's back disappears.
Continuity mistake: 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. (00:55:45)
Continuity mistake: When Jameson is talking about the headlines regarding Spider-Man, the pencils in the cup keep changing positions between shots. (00:56:00)
Continuity mistake: 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. (00:41:25)
Continuity mistake: When the part of the balcony where Mary-Jane is starts to break, there's a lamp on it. It vanishes the following shot, then reappears some shots later. (01:07:05)
Continuity mistake: This is towards the end of the scene where Mary Jane had an encounter with the thugs and Spider-Man comes to save the day. 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. (01:17:15)
Continuity mistake: 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. (00:03:35)
Continuity mistake: 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. (00:49:40)
Continuity mistake: 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. (00:33:15)
Continuity mistake: When Peter and his uncle are talking in the car, they are parked on the side of a one way street, with their car in the same direction as the traffic, but when the camera is on the uncle, you can see cars going in the opposite direction reflected in the windows behind him. (00:33:10)
Continuity mistake: 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. (00:15:30)
Continuity mistake: In the final fight scene, between Spider-Man and Green Goblin, when Spider-Man goes down, suddenly Green Goblin has a kind of weapon on his hand, when in the rest of the fight scene he had nothing. (01:46:55)
Continuity mistake: 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. (01:44:40)
Continuity mistake: 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. (00:19:10)
Continuity mistake: The Green Goblin is impaled by the knives on his glider which are shown after they have punched through him and the brick wall, but there is no blood on them. (01:49:50)
