Continuity mistake: In the scene where Dakota is having sex with Aubrey's boyfriend, it specifically shows that her bra is off. Once they finish, and she is getting off of him, she is covering her chest with the sheet. When she does this, her side isn't covered and you can that she is now wearing a black bra.
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: 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)
Visible crew/equipment: When Ingrid sits at the vanity table in the bedroom, in the shot just after Gregorio's screen reads, "Type password," but just before the close-up of Ingrid's fingers typing on her makeup, there is a lovely reflection of a crew member behind the camera, which is perfectly clear in the mirror to Ingrid's right. (00:07:30)
Continuity mistake: When the dry cleaning arrives and Holly lays it out on the table, right behind her is the large flip-over wall hanging, with a picture of balloons. When she pulls the leather jacket out of the plastic, the wall hanging is flipped open to a picture of a bird. (00:53:10)
Continuity mistake: During their sightseeing in Italy, Sarah and Tom pose for an artist who sketches the two of them. In the first shot, their portrait is tacked on the left of the easel with two other portraits. In the next close-up, their portrait is tacked on the right of the easel. (00:55:30)
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: When John says, "You offend reason sir," Peter floats up. The large light fixture is hanging from the ceiling. However, in the next shot facing Peter when he says, "Just think happy thoughts," where is the light fixture? It's gone so Peter can fly around the ceiling, but it's back again in later shots. (00:21:15)
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)
Visible crew/equipment: During the "full attack" at the start of the Battle of Stirling Bridge, Wallace repeatedly shouts, "Hold," and in the wideshot right before Wallace finally shouts, "Now!" as the horses gallop towards the right side of the screen, we can see a white car at the left side of the screen.
