Continuity mistake: As the FBI and Richard Gere rush to the hospital to save the First Lady they are flying in a helicopter. You see a shot of the helicopter flying over buildings then it cuts to dialogue inside then back to the landscape shot. However in the first shot the helicopter carries the number "28" on the side. When it cuts back after the dialogue it has "29" on the side of it. (01:36:35 - 01:40:00)

Continuity mistake: 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. (00:05:55)
Continuity mistake: In the scene where Harry and Marv are at the skating rink, the front of Marv's hair is constantly changing from shot to shot. It's either poofy or pulled back due to the earmuffs he's wearing.

Continuity mistake: When Will Smith and the other recruits are taking their written tests, the white table first appears to be situated between the second and third men from the left.

Continuity mistake: In the scene where John commits suicide by slitting his wrist, the soles of his shoes go from brand new and unmarked (quite clearly seen in a couple of close up shots) to scuffed and worn (also seen quite well in a couple of shots). (01:34:25)

Continuity mistake: After Stark is paralysed and slightly recovers, he goes to get his energy. Right then the blood around his left ear has vanished. Being seconds away from dying, the last thing he would think of is taking a shower.
Continuity mistake: When Regina becomes angry, and writes the horrible message in the burn book about herself to frame Cady and the others, the handwriting changes between shots. Look at "DO NOT TRUST HER" and "She is a fugly slut." - The handwriting changes noticeably, and "fugly slut" changes a lot - she writes it so the "g" and "y" have curled ends, yet it cuts to her sticking her photo in, and the ends to the tails on the "g" and "y" are straight. The line under "fugly slut," and the exclamation mark both change too. (01:00:15 - 01:00:45)
Continuity mistake: When Nicolas Cage drives through the window in the yellow Ferrari and the shot changes, he is coming out from a different window than in the first shot. In the first shot he emerges from the window to the left of the 7th Street Garage storefront ('Classic Autos' written on the window), but next shot he emerges from the window to the storefront's right. Also, note the now glassless window to the storefront's left, due to a previous take.
Continuity mistake: Just before Flynn cuts off Rapunzel's hair, there is a shot from behind him and he reaches up with his right hand to push her hair behind her ear. His arm is visible up to his forearm and the shackle is nowhere in sight. However, in the next, wide shot, the shackle is suddenly up around his wrist. (01:01:20)
Continuity mistake: When the girls figure out that Knox is after Charlie, and Dylan thinks of the picture and they zoom in onto "Townsend." The shot before the final shot of the photograph shows Knox's father's arm around Charlie, when in all the other shots, he has his arms above his head. (01:00:05)
Continuity mistake: When Adam pounds on Zep with the toilet seat, he grabs his shoulder in pain. In the first shot of him holding his shoulder, his hand is soaked in blood. In the second shot, however, his hand is much cleaner. (01:30:25)
Visible crew/equipment: When the guy on the roof stands and takes aim at the window in preparation for Brian, the film crew are reflected in a window behind him. (00:13:00)
Visible crew/equipment: In the scene during the American bandstand, at the end of the song when the teacher is dancing in front of the band members, the crews can be seen. The dressing and the hair doesn't match Grease era at all, and someone is sitting on a director's chair as well. (01:06:20)
Continuity mistake: When the statue of Liberty is about to crash on the street, a close shot is seen of jammed cars and hysterical people. When the shot changes to Superman flying to the rescue, the jam, the cops and the people have disappeared, and all is nice and quiet in Metropolis.
Visible crew/equipment: When Benedict snaps his fingers and the dogs form a pyramid to show how well they are trained - look at the dog's feet and you can see the rails that the dogs are standing on. (00:43:50)
Continuity mistake: When Maya enters Peter's office for the first time, you can see that he had just written something on his laptop. While they talk, you can see the word-program on the computer screen: it shows one page. Cut to Maya, then back to Peter: it shows two pages. Another cut: one page. This happens two or three times throughout the scene. (00:29:30)
