Corrected entry: When Josh is spending that first scary night in the hotel, and hears a gun shot, a shrill scream follows, and it doesn't really sound like someone on the street screaming. The exact same shrill scream is heard near the end of the film during the shot of the roller coaster at the park when it loops upside down.
Corrected entry: Big Josh calls his mother at her house to tell her he's okay. Although it's not likely there would be police stationed physically at the house, they would almost certainly have put a tracer and/or recorder on the phone, which can be put in place and then checked periodically. The call would have then been traced to Josh's workplace.
Corrected entry: Toward the end of the movie, while Josh is at Susan's house, he pulls out the video game disk that he was playing at the beginning of the movie, plugs it in, and the game picks up where he had left off. Josh's mom rushed him out of the house so quickly, there's no way he had time to take any personal belongings...much less a video game disk.
Corrected entry: When Josh is applying for the job, he puts down Billy's locker combination as his social security number. When he is told that he is missing a couple of digits, he adds '12' and they accept it. But that's only eight digits, and social security numbers are nine digits. He's still missing a digit.
