Sinister (2012)

Deliberate mistake: Nearly every night scene inside the house is lit by very bright lights shining in the windows from outside. Yet every time anyone is outside the house, it's still just as dark. There is no light source from which these lights could possibly originate.

Revealing mistake: IChat is used to make a second call to Professor Jonas, only this time we can see Professor Jonas is online under "Bonjour". Without too much detail this would mean that Professor Jonas is in the same house (on the same LAN) as Ellison. (01:31:55)

Continuity mistake: His best selling novel changes in quantity on the shelf in his office. After he signs a copy for the officer they increase in number, and lean one way then the other.

Trivia: A 2020 study by The Science of Scare Project determined this to be the scariest film of all time, based on the heart rates of viewers. However, it should be noted that this study only used a sample size of around 250 people.
