Continuity mistake: At the very beginning of the movie, the kids are trying to wake Coop up by singing to him. We see an overhead shot of the kids and the redheaded boy without a shirt on is to the right of the boy with the tennis racket. The shot changes and the red headed boy is now on the left of the kid with the tennis racket. (00:02:40)
Revealing mistake: At the start, when the girls in the bunk are standing in front of the mirror, the first shot of them looks as if the camera is facing the mirror and we're seeing their reflection, but note that neither the buttons on Alexa's blouse nor her white bracelet are on the opposite side. The "mirror" is actually regular glass with the girls standing behind the glass to mimic a reflection, though Alexa's blouse and bracelet reveal the secret. (00:03:05)
Continuity mistake: When Katie tells Coop she is going to find him a woman, his sweatshirt strings aren't visible. In the very next shot both strings are hanging out. (00:05:45)
Continuity mistake: When Coop tells Katie he's going to cancel the order of onions and limburger cheese, there's a girl with a red and white striped shirt passing by him on his left side. The shot changes to Katie, and when it goes back to Coop, the same girl is passing him but on his right side now. (00:05:50)
Continuity mistake: At the beginning of the movie, when Beth is talking to Henry for the first time, she says, "Space: the final frontier," and Henry's hands can be seen in the shot. He's holding them high and out while playing with the handle of the shovel. In the very next shot, both of Henry's arms are down by his waist. (00:07:40)
Continuity mistake: When Victor and Coop are in line in the cafeteria, Gary brings out a whole tray of potatoes. When Victor is watching Abby lick the spoon, the potato plate is completely empty. In the next shot, the plate is full again. (00:10:10)
Continuity mistake: When Andy throws his food all over the floor, he doesn't knock his cup or the napkin onto the floor. But when Beth orders him to clean up his mess the cup and napkin are missing from the table. (00:18:50)
Continuity mistake: When Beth is talking to all the camp counselors on the steps, the nurse suddenly disappears from the steps. This is evident when they are all walking away she cannot be seen where she was sitting earlier. (00:21:50)
Continuity mistake: Right before Beth drives into town, the nurse runs down the hill to stop the car. When the nurse runs down, she runs past all the camp counselors sitting on the lawn to reach Beth who is parked directly in front of them. After the nurse runs away, you see the counselors run towards Beth's car, but at this point Beth is parked in a totally different spot, to the right of where they are sitting. (00:29:55)
Factual error: Nancy is sitting on the porch knitting, however the orange and yellow blanket she is working on is crocheted. These are two very different crafts and crochet items can not be made with knitting needles. (00:30:00)
Other mistake: Victor and Neil leave in the Rally STX van to take the boys to Moose River. Later, when Beth goes into town the license plate number is '566 241' on her Chevy pickup, but when Victor drops Neil and the boys off, we see their Rally STX has the same license plate number '566 241' as well. (00:30:40 - 00:36:40)
Continuity mistake: When Aaron is telling Gail that men are insensitive, the girl next to him is playing with an arts and craft toy and in one shot the yellow feather is on top of the toy, in the next shot the feather is on the right hand side. (00:35:00)
Visible crew/equipment: When Victor and Neil arrive at the campsite, Neil opens the front door of the van and you can see a crew member's reflection. (00:36:00)
Continuity mistake: When Victor is driving away from the campsite to meet Abby, the driver's side window is up. After he crashes into the tree the window is completely down, and it wasn't shattered in the crash because the second after the crash the window is still up. It's only when the shot changes that the window is down. (00:36:40)
Revealing mistake: When Neil is in the raft with the boys talking about wanting Victor back, just as Neil climbs into the water we can see the safety cable attached to the back end of the raft. (00:38:30)
Continuity mistake: When Susie is complaining to Beth about Steve being in the talent show, at the end of the scene a hot dog appears in Ben's hand out of nowhere, as it wasn't there in any of the other shots of the scene. (00:46:30)
Continuity mistake: When Andy is standing by the table, Lindsay comes over telling him that she wants to make out, but he's all disgusted because she has BBQ sauce all over her face. For the first few angles of the scene, the BBQ sauce is on the corner of her mouth, and on the side of her face a little. But in one angle, it is ALL over her mouth. Then it comes back to the previous angles and it is back in the corner of her mouth again. (00:49:15)
Suggested correction: They keep adding more sauce intentionally for comedy.
Continuity mistake: At the very end of the capture the flag game, Coop and McKinley can be seen chasing the guy holding the flag. If you look at the other people running there's a guy in a bright red shirt and between shots he keeps switching between being on the right side of McKinley and the left. (00:51:05)
Continuity mistake: When Coop runs to Katie's cabin and sees her talking to Andy, right before he runs up the steps you can see the cabin door is closed. The shot changes and suddenly the door is wide open. Also when he runs up it's sunny, but when he's talking to her it's raining, then it's sunny when he's running off. (00:57:25)
Continuity mistake: Right after Gene knocks Susie over with the door, the shot changes to a group of kids sitting against a wall. Notice the kid in the blue tie-dyed shirt and glasses. When the shot changes back to Gene, the same kid can be seen sitting at the end of the table next to the kitchen door. (01:01:50)
