Continuity mistake: The protagonist just arrived to his college. Long shot as he gets off the taxi, and to the right of the frame you see a group of 3 girls crossing the street and walking on the lawn. Cut, and the 3 girls have yet to cross. (00:07:00)
Continuity mistake: Kelly was wearing a white thermal top over a white sleeveless undershirt. After he was thrown into the garbage can, his white thermal top was wet against his back, so he was no longer wearing the undershirt. (00:03:54 - 00:05:43)
Continuity mistake: Take notice of the desk lamp as Charlie and Al are talking in Charlie's new office. As the camera switches back and forth between their face to face conversation, the green glass cover of the light keeps changing position too. This happens even after Al leaves. This was probably done to keep the light out of the camera during filming. (00:13:50)
Continuity mistake: While sitting on the couch, Peter suddenly has a clump of hair sticking up near the back of his left-sided part that disappears but reappears after some camera shifts. (00:01:20 - 00:01:42)
Continuity mistake: Daryn starts running/jogging in summer foliage. Autumn foliage is shown in an aerial view, then it switches back to summer and Daryn is running on the street. When Daryn says "bye" to Ms. Murdoch, there is spring foliage behind him but summer foliage behind him when the camera shifts. It is one timed-running session and he is wearing the same clothes. (00:01:30 - 00:02:28)
Continuity mistake: When Dellinger is about to leave home to Chicago her wife's hand swaps between being on the boy's shoulder or over his left bicep.
Continuity mistake: When the Homeland Security guy is sitting in the lobby in Vancouver, Canada, a girl and another man are walking behind him and across the lobby in the wide shot. But when it zooms in on him, the same people and more are walking behind him again as if they never were crossing the lobby. (00:28:45)
Continuity mistake: Views of Michelle's car wreck were inconsistent. When the car veered to the right and was headed toward the tree, the driver's view showed most of the car was to the left of the tree trunk. On impact, it looked like the right side headlight hit the middle of the tree trunk. Michelle got out and a rear view showed the tree trunk roughly lined up with the steering wheel (i.e, more than half of the car was to the right of the trunk). After impact, both headlights were shining in front of the tree.
Continuity mistake: Numerous times throughout the movie, the blood splatter on Sam's face (especially noticeable on the right side and above her right eyebrow) varied. For example, sometimes the blood above her eyebrow was straighter compared to usually arched and the length, width and/or vividness of the red "blood" changed (perhaps due to filming on different days and/or re-applying/ refreshing the make-up). (00:49:07 - 01:33:36)
Continuity mistake: First argument. Leilani shouts "Why are you being so loud right now?", with a hand behind her neck. She does not start the next shot in that position, she puts her hand there only a second later. (00:04:05)
Continuity mistake: The fragments from the truck's taillights that Cassie smashed with a tire iron were obviously "neatly rearranged" (and looked resized to be more uniform) before showing them after the man drove away. Cassie hit the outer sides of the rear taillights and fragments of various sizes scattered, so all would not settle close together along the bumper. One large fragment from the passenger side flew past Cassie behind the truck and landed about three or four feet away but was not there afterwards.
Continuity mistake: The view of the restaurant and other businesses along the same street are quite different when Pedro exits the restaurant compared to a little earlier when Emma brought Oak the guitar. Store fronts are not the same, the position of a garbage can changes, the restaurant has some outdoor tables and umbrellas, and there are brick borders around the trees and garbage cans. (00:12:34 - 00:14:18)
Continuity mistake: The appearance of Grace's house by the front door (to the left of the screen) changes from the time Billy is standing along the road to when he meets his mother half-way. At first, the side of the house is mostly white; it is mostly brown thereafter. The garage area to Billy's left also changes color from brown to white. (00:05:22)
Continuity mistake: The three friends are at the hospital. As Raissa and Katia predicted, Dr. Victor is hitting on Paula. As they follow him, the stethoscope around Raissa's neck dangles differently from her neck between cuts, with the cup on top of her hair or under it, closer to the shoulder. (00:05:35)
Continuity mistake: Mikey and his friend are smoking the same inch-long joint by the back door which gets passed back and forth - no way they could keep holding/smoking it for that long given how short it was to start with. (00:04:50)
Continuity mistake: The same couple are sitting behind Alex and Greville when they attended Cinderella and Swan Lake ballet at two different times.
Continuity mistake: The scene where Poseidon uses all of the snail and a random fish sends the snail down the chute. When SpongeBob and Patrick look through the window it is the Chancellor sending the same snail down the chute. (00:17:00 - 00:39:00)
Continuity mistake: When the family stopped along the road for a break, the car towing the camper was parked diagonally to the left (not aligned with the camper). The car was visible behind Alan when he was talking to Ben, but it was not when Alan was walking toward Tyler and Charlie. Also, Alan and Ben were at various distances from the camper. (00:13:16 - 00:14:20)
Continuity mistake: After PJ lets Officers John and Julia inside, there are a few continuity errors with the box on the table and the lamp's cord. Initially, the white evidence box is flush with the counter and the front side (with a hand slot) is facing the lower right corner of the screen. Later, the box is closer to the edge and the front side has been turned about 45°. The lamp's cord is sometimes flat on the table but other times there are two upward loops. The box and cord each change a few times. (00:34:09 - 00:35:15)
Continuity mistake: The belongings that the half-brothers packed into the cargo area of the vehicle are inconsistent many times during their trip. Sometimes, none of the belongings can be seen through the windows. (00:28:09 - 00:57:45)
