“Paranormal Activity 4” Trailer: Katie Is Back

By now, it's clear that the “Paranormal Activity” franchise isn't making any efforts to welcome new fans with the new installments it gets. That's ok, as long as you're one of the fans.

Above is the full trailer for this year's sequel, “Paranormal Activity 4,” which was teased earlier this week.

Fans will already know that “PA” 2 and 3 were like prequels (for lack of a better term) to the original film, in the sense that events in 2 preceded events in 1, while 3 was before both.

4 is moving forward to show how the curse in the previous installment is expanding to other houses. And yes, Katie does make an appearance!

“Paranormal Activity 4” will be out on October 19.
