Other mistake: In the door vault scene, Boo's laughter causes all the red lights on the doors to generate and fully power. Unlike the other two scenes - back at the apartment and the trash compactor - this resulted in a blackout. (01:09:09)
Suggested correction: In the house and at the compactor, it caused an overload. This resulted in a blackout. The doors seem to work differently.
Other mistake: The scare leaderboard shows scarers by their surnames, except Randall, who is shown by his first name only.
Audio problem: Jerry counts down from seven. When he has to say one his mouth opens, but he doesn't actually say one. (00:14:38)
Suggested correction: Many times when counting down, three-two-one is silent.
Especially when filming something like this, so the numbers aren't accidentally recorded.
Continuity mistake: When Mike is performing his standup routine in a boy's room near the end of the film, his eye quickly switches from green to blue, and then back to green right before he says "your room."
Continuity mistake: When Sully and Mike are practising, their chairs are switched. Sully's is on the right Mike's is the left. When they sit to watch the commercial, they are switched back.
