Factual error: During the breakfast scene with the bacon a box of Cheerios is seen on the counter with the red check mark on it. This indicates that the cereal is American Heart Association approved. The check mark campaign didn't begin until 2009 even though the movie supposedly takes place 3 years prior, in 2006.
Paranormal Activity 2 (2010)
1 factual error - chronological order
Directed by: Tod Williams
Starring: Katie Featherston, Molly Ephraim, Micah Sloat, Brian Boland, David Bierend
Continuity mistake: During the last night Martine is working for the Rey family, she is shown saying prayers in the kitchen and TV rooms. During that time, the kitchen camera shot has knives, spices and a chopping board on the counter, but in the next kitchen shot, everything is replaced by a fruit bowl. You'll also notice that the hanging pots and pans change in number, order and colour and the flowers located on the table change variety and also too the bowl/vase.
Daniel Rey: We just can't let this affect us that much. If we do that, the terrorists win.
Trivia: Notably, the previews for this film (and several other sequels in the series) contained footage not seen in the finished movie. The previews were often made primarily of footage from alternate and deleted scenes. The producers and directors hinted that this was done to help keep the story secret, despite being a bit shady on their part.
