If things go on this way, by the time we get to Paranormal Activity 10, it’ll be set in 1875, with people having ‘shot’ weird stuff going on with old-fashioned camera. Paranormal Activity 2 was a prequel to the first film, and number three will be set before the second, so we’re certainly making our way back in time. There’s not much plot info available, although as the poster suggests we’re going to have kids in peril this time around, with the little ones in trouble being a young version of Katie from the earlier movies, as well as her sister, Kristi. The movie, directed by Catfish helmers Henry Joost and Ariel Schulman, will hit cinemas at the end of October. Click here for the teaser trailer.
