Revealing mistake: Lily was sitting in the back seat of Andrea's small sedan with her head out the window. Part of Lily's friend's upper left body could be seen to her right but the rest of her body was made to appear as though the door frame was blocking it from view. In alternate shots, the friend's upper body is side-by-side with Lily's - but no sedan has a window that wide, the door frame was not there, and the friend would not be able to sit in a back seat like she was because of the driver's seat.

Revealing mistake: At dinner, Chris said he is thinking of trying to escape. There is another table of diners behind him and a window can be seen in the background. The corner of the room can also be seen near the far right of the screen. JP and others turned to look at the window then the window was shown. But it could not have been the window that was behind Chris (there're no obstructions) and the kids' eyes would have been gazing toward the corner of the room. (00:31:19)
Revealing mistake: The owl that JP saw was obviously "fake" (stuffed or CGI). Its nose was crooked and its puffy cheeks made it look like it had cheek filler injections; owls have flat faces. (00:32:50)
