Other mistake: At the beginning, when everyone is watching Shelby fighting on TV, the timer is going too slow. According to the timer, the fight ends at 2:53, which is only 7 seconds of fighting, yet the fight was way longer than that.
Continuity mistake: Sam hires a personal chef, Sonia. When Carly, Sam and Freddie are sitting at the table and Spencer is talking to them, Sonia takes the blueberry muffins out of the oven and puts her oven mitts down. Next, Spencer starts walking away. Then Sonia is putting down her oven mitts again. There is no way she could pick up and put down her oven mitts that fast. (00:13:15)
IMeet Fred - S2-E10
Character mistake: Carly says Shelby, ID Is 4 hrs away. It's more like 11 and a half hours from Seattle.
Other mistake: When the military barge into Nevel's house, Uncle Roger puts the camera down and you can see it not moving whatsoever, but in the shot from the POV of the unmoving camera the shot is moving.
IHeart Art - S1-E14
Continuity mistake: When Spencer is working and the dentist pushes back the tongue and his saliva sprays on Spencer, you can see that every time it switches back to Spencer, the wet stain on his shirt decreases in size.
Revealing mistake: After Sam shoots Spencer with her blowgun, she lands on the ground after jumping from the ceiling. During this shot, you can easily see that it is a stunt double.
Continuity mistake: In the beginning, Carly gets a bowl and fills it with popcorn up to about 2/3 full. The camera cuts to Sam, then back to Carly, and the bowl is barely full. The camera goes back to Sam then to Carly again, and the bowl is 2/3 full again. Freddie walks in, and the bowl is barely full again, which Carly now fills with popcorn.
Continuity mistake: When Carly's cousins come over, Sam goes upstairs to read a book. When her cousins are gone and Carly goes upstairs, she sees a boy rubbing Sam's feet. In between shots, Sam's right foot goes from facing inwards to being flat.
Plot hole: Near the end, Sam locks Mr. Howard and Ms. Briggs in a closet. Sam and Gibby then put a heavy desk right against the door and leave them stuck inside. Then later the two teachers are seen frantically controlling the students. How did they escape? They were inside a closet with the door locked on the outside and with a heavy desk against it.
Suggested correction: It's clear that another teacher or teachers heard the announcement or heard them yelling and let them out... What we should be asking is why no other teachers helped them control to the students.
Continuity mistake: In "iGo to Japan", when the iCarly crew, Spencer and Freddie's mom have to jump out of the airplane, Freddie's mom jumps out of the airplane with out buckling the parachute backpack in a rush to follow Freddie. But when everyone has landed, she is struggling to unbuckle and take off the backpack.
Continuity mistake: When they have the first meeting with the techfoot people, Sam is eating a sandwich. Every time the shot goes back to her and Carly, the amount of the sandwich she has eaten changes. Sometimes there is a bite taken, and then the next time there isn't a bite taken out of it.
Revealing mistake: Carly, Sam and Shelby all corner Nevel in the ring. If you look in the corner where Shelby shows up, she's not in that corner until the light flashes on her.
Revealing mistake: It's very obvious that Carly's grand-dad is a stunt double when he does a handstand in the record attempt episode.
IWanna Stay with Spencer - S1-E5
Other mistake: The "Fan of Hammers" has all the hammers pointed the same way. But when the hammer goes into the wall, it goes in backwards. It is also there through all the rest of the shows and even in season two, where in "iKiss" it has a black handle. (00:02:35)
Revealing mistake: When the gang is "Messing with Lewbert" and they zoom in on his wart, you can easily see it is just makeup.
IQuit iCarly - S3-E8
Continuity mistake: Carly, Sam, Fleck and Dave are sitting at one table at the Groovy Smoothy sipping a new smoothy flavor with T-Bo standing next to them. Suddenly the smoothy gets too spicy so all four go to another table and gulp down other people's waters then sit back down. The waiter places two glasses in front of Dave and Fleck. The waiter starts to pass behind T-Bo with 2 more glasses of water, but the shot immediately cuts to Sam and Carly drinking water.
Visible crew/equipment: In the iCarly TV movie "iGo to Japan," the gang is riding in Kioko and Yuki's car when the Japanese comedians start arguing. In the shot showing Freddie putting his camera away, you can see several reflections on the side of the car. They are hard to make out what they are, but these are obviously the reflections of the crew in the background. If you look out the window beside Carly and Sam in the same shot, you can see how fast they are going past Tokyo. If these reflections are reflections of things in the city, they would quickly move away as they speed past. However, they stay put.
Continuity mistake: When Sam, Carly, and Ernie the dance coach are backstage hearing about the talent competition, his hands and clipboard move position from shot to shot.
IStage an Intervention - S2-E2
Visible crew/equipment: When Carly and Freddie are talking in the hallway about his bad luck, you can see a crewmember's shadow on the wall next to Freddie.
IStage an Intervention - S2-E2
Visible crew/equipment: Every time the shot shows the chair between living room and kitchen (when they show where the chair is), the reflection of the studio light is seen on the bottom of the chair. For example here when Carly looks at Pack Rat, when she walks, you can see the studio lights at the bottom of the chair.
