Corrected entry: In the scene where Andrew and Bender are about to get into it, Bender pulls out a switchblade, and stabs it into a nearby chair. The shot goes back to Andrew, and then goes back to Bender. In this shot, the switchblade is not stabbed into the chair.
Corrected entry: Various times throughout the movie, Judd Nelson is wearing the diamond ear ring Molly Ringwald gives to him when her parent picks her up from detention at the end. It is very different than the lightening bolt earring, so there's no way to confuse them.
Correction: He's wearing an ear cuff which you can see when he puts on Claire's diamond earring.
Correction: He is wearing other earrings in his ear that were also most likely given to him by other girls.
Corrected entry: When Allison is sitting and biting her nails at the start, she is sitting facing away from the other students, but then when she notices Bender, Brian, etc., staring at her she is suddenly facing the front.
Correction: Allison faces away from the students, however as she notices them staring at her, she moves her upper torso to look at them, and then spits at Bender after his comment. Her lower body does not move.
Corrected entry: When Andrew does his run around the second floor of the library he passes by a state flag with a confederate emblem on it. The film is supposed to take place in Illinois, that state was part of the Union, not the Confederacy.
Correction: This isn't a mistake. It was the Georgia State flag. But the library has several different flags that we see, so it would make sense the library simply had all the State flags hanging around. Not to mention this was filmed in an actual Illinois high school.
Corrected entry: Throughout the movie, Bender is wearing a lightning bolt earring in his left ear. However, at the end of the movie when Claire gives him her diamond stud, and he goes to place it in his ear, the lightning bolt is gone. (00:20:15 - 01:34:08)
Correction: Bender's lightening bolt earring doesn't just vanish between shots. The fact is, Bender and Claire have been offscreen for quite some time before the closeup of Claire's hand placing her diamond stud in the palm of Bender's hand. We didn't actually see Claire removing her diamond stud, but we know that she did it, offscreen. So while Claire removed her own earring, she told Bender that she wants him to keep it, and he removed his. Viewers do not need to see every single moment onscreen.
Corrected entry: Bender has one white shoe on and one black shoe on in the gym, but the scene before he has 2 black shoes on.
Correction: It's clear he found some gym shoes and put one on to be weird.
Correction: You can see him take it off when Vernon throws the basket ball at him and also you can see him pick up his jacket and left shoe when avoiding Vernon.
Correction: In some scenes he has a black boot and normal shoes and others two normals black shoes and then in the gym he has a black shoe and white shoe but when he leaves the gym it falls off leaving him in one black shoes but then in the science on the statue you see he had two black shoes on.
Corrected entry: In the scene where Vernon goes over some rules with everybody, Brian momentarily switches seats. Then, from one shot to the next, he's suddenly adjusting his coat. (00:06:30)
Correction: He moves to the chair next to him, however, he then moves back to his original seat straight after, due to Vernon saying, "No moving seats." In the next scene, he is adjusting his coat in his original seat.
Corrected entry: The door to the library is closed and Vernon is in his office across the hall, so why can't he hear the music blasting from the library during the music and dancing scene?
Correction: During the dancing/music scene, Vernon is downstairs with Carl in the basement, looking through files and talking. Therefore, he wouldn't hear the music.
Corrected entry: In the scene where the five are running through the halls trying to dodge the principal, they run past a window where it is full-on dark. Since the detention took place on a Saturday morning and afternoon, there is no way this could have actually happened.
Correction: At least one of the scenes with the dark window is correct because the window was NOT an exterior window. You can see that it is simply a window to another room in the school. This would be dark since the lights would not be on.
Corrected entry: Molly Ringwald's hair changes styles in just about every shot.
Correction: She could have easily pushed it away or shaken her head. It isn't fixed with hair spray.
Corrected entry: During the scene where Mr. Vernon asks for Andrew's help in putting the magazine rack in the doorway, he tells Andrew to be careful of the magazines when crossing back. Naturally Andrew slips and crushes some of the magazines. However, all Andrew had to do was use the adjacent door. Even if it was locked from Andrew's end, Mr. Vernon could have pushed it open for him on his end.
Correction: The adjacent door is also blocked by the magazine stand. (The stand is wedged between the two doors).
Corrected entry: When Ally Sheedy is pouring the straws with sugar in them onto her sandwich, at first she has three straws in her hand, but after the close-up of the second straw being poured it shows her without the last straw in her hand. (00:38:44)
Correction: Ally Sheedy is seen only pouring two straws of sugar in, however in the frame when she is putting the packaging in the Coke can, there are three empty straws. The one that may have "disappeared" was applied to the sandwich off-screen.
Corrected entry: In the shot where the principal is talking to John in the closet, he takes off his suit coat. When he leaves the closet you see him pick something up (I think the coat) and he's wearing it when he's in the bathroom. When the shot goes back to John escaping, it shows John's jean jacket and a suit coat just like the one the principal has lying next to it. If he took his coat then why is another coat left there? I doubt he had two on.
Correction: Bender was wearing a trenchcoat over top of his jean jacket. That's the '2nd' jacket you are refering to.
Corrected entry: When John Bender (Judd Nelson) is in the gym shooting hoops and the teacher (Dick) comes in, Bender is wearing a white tennis shoe on his left foot and a black boot on his right foot. His white shoe comes off and is left in the gym so he's then only wearing one black boot on his right foot. The next time you see him and for the rest of the movie he is wearing black boots on both his feet. Where did the left black boot come from?
Correction: Watch the movie from the beginning. Bender arrives by foot, wearing his own, dark, shoes. Bender most certainly found the white shoe in the boys' changing room on his way to the gym. Remember the opening scene even shows that there're sneakers and apparel left on the floor.
Correction: Watch closely when Bender tries to get around Dick (excuse me, Rich) to leave the gym and return to the library. He makes a "fake out" sort of move, toying with the teacher, and picks up his second boot and jacket as he does so.
Corrected entry: A Shermer High School newspaper is shown with the headline "Clarke Sparks Grapplers." In the credits at the end of the film, Andrew's last name is spelled Clark.
Correction: So the newspaper made a typo - a mistake within the "world" of the movie, not a mistake (necessarily) of the filmmakers.
Corrected entry: Following the scene where Bender shoves the "wad" down Brian's pants, we see him running past rows of lockers. As the camera aims to show the angle of the hallway, he heads towards a full-dark window. This isn't possible, since the detention was held during the daytime.
Correction: The window you are talking about is a window to another room, not an outside window.
Corrected entry: After Claire gives Allison a makeover, Allison is wearing different clothes. Where did the clothes come from? Did they go shopping in the middle of detention?
Correction: The skirt was worn by Allison since the beginning, the belt was from Claire, and the white shirt was either in Alison's bag, worn underneath all her black stuff (it is winter, after all).
Corrected entry: In the scene where Bender is in the gym shooting baskets, the teacher kicks the ball and Bender jumps out of one of his sneakers. You can see him slip the shoe off before he jumps out of it.
Correction: This is not a mistake, he leaves the sneaker purposely.
Corrected entry: Towards the end of the movie Allison reveals that she's attending the detention simply because she has nothing better to do. This was probably done to emphasize her being a loser with no life, but it's ludicrous in realistic terms. Vernon would have surely had a list of the students scheduled for detention, and would have immediately realized that one extra student was there who had no business being there. And as far as I know there is no High School that would allow a student to sit through a detention session just for the fun of it.
Correction: Allison also states she is a compulsive liar.][Vernon didn't know her name either, it's possible that she wasn't supposed to be there and he didn't care.
Corrected entry: The time on the clock in the hall is way different from when the troublemaker guy runs down the hall than the on the clock in the gym when we see him a second later shooting basketballs.
Correction: When the janitor/custodian first talks to the group he mentions that the library clock is fast 20 minutes. This could explain the discrepancy between the library clock and the gym clock.
Correction: Absolutely wrong. You see Allison Reynolds' (Ally Sheedy) hands reach into frame and take the knife.
