If you live next door to a creepy kid who can manipulate electricity, maybe go with your classic deadbolt lock, instead of the automated house-of-the-future talking door. Take a look at the trailer for Paranormal Activity 4:
The super creepy-looking horror movie once again stars Katie Featherston as the possessed 'Katie,' though her specific role in 4 is unclear. From the trailer, it looks like the new film takes place in November 2011, a year after the events of the second film.
Paramount is keeping the plot details pretty far under wraps. Paranormal Activity 4 is directed by Henry Joost and Ariel Schulman, and hits theaters October 19.
