Spider-Man (2002) - 162 mistakes

Continuity: 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.

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.

Other: During the 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.

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.

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.

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: 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: 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.

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: 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.

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.

Audio problem: When Mary Jane is about to fall from the balcony and the Green Goblin appears in front of her, we hear him say, "Hello, my dear," but his mouth is not in sync with those words.

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 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.

Revealing: 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 close, you can tell 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 quick to be at normal speed.

Revealing: 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.

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.

Continuity: 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.

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.
