Continuity: Jameson is sitting in his office when another man bursts through the door. Jameson jumps and turns to look at him twice- first in the wide shot, and again in his closeup.

Continuity: In the cafeteria Peter web-slings a tray, with hardly any corn on the plate. Then Peter flips it onto Flash and suddenly there's a whole lot of corn on his back.

Continuity: After Peter punches Flash in the guts during the Flash/Peter Hallway fight scene, the camera shows Mary Jane in a closeup scene looking surprised. Look behind her on her right and you will see a surprised fat man wearing glasses. After Flash's friend says "Jesus Parker, you are a freak," and the camera shows Harry saying "Wow, that was amazing", you can see the same fat man suddenly appearing on the left of Mary Jane looking happy and clapping. Immediately afterwards, the camera then shows Mary Jane in a closeup again and voila, the fat man appears back on Mary Jane's right, near her, and looking somewhat surprised again.

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 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 MJ kisses Peter in the cemetery, his head is leaning towards his left, and in the next shot, his head is leaning towards his right.

Visible crew/equipment: When Mary Jane is on the balcony at the Oscorp Festival and the Green Goblin causes part of it to start falling apart, the wires and chords causing the balcony to fall down and pull back up can be seen.

Revealing: 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.

Continuity: 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?

Revealing: Green Goblin never actually presses any of the buttons on his costume, so how does he operate the glider?

Continuity: In the final fight scene between Green Goblin and Spider-Man, the damaged eyepiece over Spider-Man's left eye keeps changing its damage pattern between shots.

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: In the scene in which Peter and Flash are fighting in the hall, Harry runs up to Mary Jane to see what is happening, seconds later Peter jumps up to avoid Flash's friend charging him from behind. In the shot of Peter flipping in the air, you can see that Harry is no longer standing next to Mary Jane, a girl in a blue sweater is. After Peter lands, the camera cuts back to Mary Jane and Harry is once again by her side.

Factual error: Why would Columbia University have the "most powerful electron microscope on the eastern seaboard" in the same lab room as it would have the spider lab, which is a biology/genetics study? Electron microscopes are useless for studying DNA. The electron beam turns molecules into sludge. All but the toughest organic samples have to be coated with metal as protection, and you can't do this with DNA.

Audio problem: In the scene where Mary Jane is about to fall from the balcony and the Green Goblin appears in front of her, he says "Hello, my dear," but his mouth says something different.

Continuity: 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.

Continuity: When we see Spider-Man protect the armoured car and take out the thieves, we see that Spider-Man throws a robber over his head and the robber hits a wall. The following shot his position has changed lying on the floor.

Continuity: 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.

Continuity: 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.

Continuity: 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.
