Paranormal Activity 3 (2011)

Factual error: During the sleepover in the tent Dennis gives the girls M&Ms to snack on. If you look closely you can see one of the girls eating a blue M&M. These didn't hit the market until around 1995, a full 7 years after this movie takes place.

Trivia: Reportedly, so much footage was shot during production, the producers suggested that they could construct an entire second movie out of the leftover deleted and unused scenes.
