The other day we had a brief teaser for the Paranormal Activity 4 trailer, and now it’s here. After following Katie and her family’s story backwards in time in the first three films, part 4 is going to move things forward, hopefully explaining what happened to Katie, and according to this trailer, it involves a blonde woman who also loves filming everything she does.We’ll be able to find out the full story on October 19th, and hopefully the story going forward will be as fun as it was going backward. Take a look at the trailer and the brand new poster (image via Dread Central) below.
