Continuity mistake: In the Karaoke scene, when it's Charlotte's turn, one briefly sees the number 601 on the door to the cabin. Later, when she's waiting outside and Bob leaves the room it's the number 602. (00:48:10)
Continuity mistake: April writes a note to Bobby on the back (note the clasp) of a manila envelope telling him about the stove being broken, but the next two times we see that note the writing is on the front of the manila envelope and the handwriting has changed. (00:22:15 - 00:33:25)
Continuity mistake: The way Tess holds the notepad, to show grandpa the message, changes between the shots. (00:11:30)
Continuity mistake: Look at the scene where Chanel and her mom are putting on face cream. In the wide shot, Chanel only has cream on her chin, cheeks and forehead. Her mom hasn't applied the cream. In the close-up (when her mom says that they might be moving to Paris), there's cream all over their faces.
Continuity mistake: After Signor Martini tries to find the snake in Frances' house he lights the stove with a match. He then places the match box on top of the stove with the long side of the box facing the camera. In the next several shots the box turns to the narrow side facing front and then back again. (00:45:20 - 00:47:00)
Revealing mistake: In the scene where Trout's gang burns the school and kills Sam, there is a part where Katherine runs into the sheriff's office then exits. A few seconds later, Katherine runs by a shop on which the name is reversed. Very obvious. (00:51:40)
Continuity mistake: When Barbara Anne's owner comes to the door to talk to Owen, she is holding a coffee mug by the handle. The next shot shows her holding the mug on the other (non-handle) side. (00:05:50)
Continuity mistake: When the Rock finally starts using guns, there is one shot where the three holes in his tee shirt are on the right side of his chest, because it is a flipped shot. The holes are on the left side of his chest in every other shot. (01:23:20 - 01:24:40)
Visible crew/equipment: In the scene where Buddy and Michael are leaving the school, a crew member is visible in the bottom left of the shot. At first, he is just standing there, but he then tries to hide inside a doorway. (00:52:00)
